Foundation Survival Kits: The Next Level

One of the blogs that I have often referred back to has been that on Foundation Survival Kits.
In that article, I suggested seven items that formed the foundation of a useful emergency kit.
These were:
• A water bottle
• A canteen cup or mess kit
• A fire kit
• A survival knife
• A blanket or poncho‑liner
• A rain‑poncho
Each of these items may also be seen to represent a theme.
In this blog, I would like to expand on these themes and reflect on what further items may be acquired to expand these capabilities.

Water

Water is the cheapest category to address. Buy a couple of bottles of soda. Once you have drunk the soda, use the bottles for water.
Soda bottles are incredibly tough and flexible. If water freezes in a bottle you can bash it around to break up the ice, with very little chance of damaging the bottle enough for it to leak.
When there is a chance that water will freeze, carry any water containers with the cap or drinking tube downwards. Ice floats, so the lowest part of an inverted bottle will be the last to freeze solid.
The soda bottle is a superior choice to more expensive, smaller, heavier and more rigid military plastic canteens. Unlike a military canteen, you can squeeze some of the air out of a soda bottle to reduce the noise of water sloshing around.
The only thing wrong with most soda bottles is the small diameter cap. It needs a little more care when refilling. It also makes it a little harder to shake broken up ice out of the bottle.
The alternative or supplement to a soda bottle is a hydration bladder. Most of these come with drinking tubes, allowing you to drink while on the move. There are drinking tubes for soda and other plastic bottles, but the ones I have seen seem to cost as much as some models of bladder with a tube.
Being very flexible, water bladders allow air to be squeezed out of them to reduce any sloshing noises. This is useful if you want to move tactically, are hunting, nature-watching or just want some peace and quiet.
Soda bottles and large hydration bladders are a great means for carrying water in your pack.
You will need some means to carry water with you when you are not wearing your pack. However, you do not want to constantly carry such a weight of water that the effort increases your water consumption.
There are hydration bladders that can be worn as an independent backpack. You cannot wear these when wearing another pack. Switching to them usually involves some unpacking or detachment.
Depending on conditions, one or two litres on your person will be about right. This may be a soda bottle or smaller, or one or two of the smaller capacity hydration bladders or bottles.
Ideal would be a bumbag/waistpack with a bladder of about 1.5 litres. Sadly, these seem rare at the moment and the examples you can find have a high price tag and are not offered in neutral or natural colours.
See the knots book for a method to construct a carrier for a soda bottle.
“Work from the outside in”. Use the water in your pack in preference to the supply you carry on your person. This policy also applies to other consumables, such as matches, emergency food and so on.
You should invest in some water purification tablets for times when you cannot heat‑treat your drinking water. It is a good idea to have a good stock of these.
There are various brands of water sterilization pumps. Given the importance of clean water, these are worth considering if they are within your means. Viruses may pass through filter systems. Water so produced may still need to be heat or chemically treated.

Cooking and Food

The topic of heat-treating water brings us to the item of a cooking vessel. I have recently written on the subject of cooking vessels, so have little to add about them here.
A cooking vessel will be more useful if you also have some form of stove.
This theme also takes us to considering the provision of food, be it rations or that procured by hunting, fishing, trapping and gathering.
An emergency is no time to worry about the diet! The food in your bug-out bag should be rich in calories, carbs and sugars. It should require very little water, cooking or preparation. It should have a long shelf life when stowed in the bag.
Ideas along these lines have been discussed on various pages on this blog.
If the 72-hour timeline of an emergency is accepted, theoretically your bug-out bag only needs half a dozen MREs or three HDRs, if you have access to them. Obviously, discard unnecessary mass such as the gum or duplicate cutlery. This is, however, an expensive option!
Your food may need to be in a bag or net that can be hung from a tree out of reach of bears. Other items that will attract their interest, such as toothpaste, cooking vessel and refuse will also need to be cached with the food. Keep about 16 metres of suitable cord with your bear bag/net.
MREs may include flameless heating pouches. You will still need your mess kit for water treatment.
Going without a cup of tea for a couple of days will not kill you, but a small brew kit may be good for morale. A hot drink may make the difference in cold weather. In addition to tea and coffee bags (vacuum-packed?), add some variety such as instant hot chocolate, soup and stock cubes.
Inside your mess tin is a logical place to carry a brew-kit.
Living on wild foods is more likely during a longer duration survival scenario.
After plant matter, fish are your most likely source of wild food.
If venturing into the wilds, carry at least ten metres of braided fishing line and a dozen or so no.12 hooks, each already attached to a foot or more of monofilament line. A third to half of those hooks should have some form of lure, such as mackerel feathers. This fishing kit gives you the capability to set up a night‑line.
If you wish, have a small fishing kit packed into something like a 35mm film container that you can easily add to your EDC. A more extensive kit, including bulkier lures, more line and copper or brass wire may be packed in a small tobacco or Altoids tin and carried in your pack. A frog/fish gig head is worth adding to your larger fishing kit, but may need to be modified so it can be used on a field-made shaft.
For active hunting of small game, your priority purchase should be a catapult/slingshot. Potentially, this could also be used to drive off threats such as feral dogs, or knock fruit or nuts from trees. If you do not have such a device, become a petrobólos and remember the ancient art of throwing sticks and stones.
Do not get a model that is too elaborate or bulky. Regularly inspect your catapult for deterioration of the bands.
Like any weapon, this will be of little use unless you put in the practice.
Your first hunting firearm should be .22 rifle, preferably semi-automatic and suppressed. A useful number of rounds may be carried for very little mass and bulk.
Openly carrying a firearm may not be prudent in certain locations. A takedown design that can be stowed in a pack has merit, if it has adequate accuracy. A small game rifle/shooter/ammo combination needs to be capable of reliably taking squirrel‑sized targets.
Many small game and birds have sharp eyes and are particularly attuned to movement. A semi-automatic allows for less body movements that might spook your target.
If forced to use the .22 defensively, the best tactic is accurate rapid fire, which also favours the semi-auto.
Examine the iron sights that come with your .22 rifle, and invest in a good set of iron-sights if you find them wanting. Learn to use your iron-sights, before you buy a scope. If/when your scope gets damaged, you will need those iron-sights.
A survival .22 may be required to defend its user or in an emergency to take targets larger than is customary for this calibre. Both of these possibilities favour high-penetration performance. Hollow‑point “hyper‑velocity” loads such as CCI Stingers are mainly intended for small game. For the survival weapon, the preference is for more conventional high‑velocity solids. These not only waste less meat, but generally cost less!

Fire

The fire kit is another low cost item, if you are sensible. Hold off from buying fire-starting gadgets and exotic tinder materials.
The best means to light a fire is a naked flame. Buy some disposable lighters.
Have a lighter on your person at all times. I keep mine in my trouser pocket so that it stays warm. Have a couple of lighters in any fire kits you construct. Add a lighter to each of your outdoor coats, handbag, and other bags you commonly carry.
You should have a lighter or fire kit in your car, boat etc. Do not assume the dashboard lighter of a vehicle will work when you most need it. The car battery may be dead.
For each fire kit, have a water‑tight container or two for tinder. Fill one with cotton wool and Vaseline. Some folks prefer wax‑soaked cotton string. The Vaseline and cotton wool that you do not use to make tinder are handy things to have around the house anyway.
To this fire kit, you can add some birthday cake candles and a Fresnel lens. (Remember that your compass may also have a magnifying lens that can be used for fire‑starting).

Toilet Paper and Hygiene

Toilet paper is a low cost, low mass and relatively low-bulk item. Carrying more than one roll is not a bad idea. Better to have it but not need it than…
Toilet paper leads us to the theme of hygiene. I have already written about washing kits and medical kits.
The common mistake with wash kits is to carry too many items, in too complicated a bag or roll.
My wash kit fits in a small mesh bag, with the toothbrush, deodorant and paste in a mesh pencil case, since it is convenient to have these separate.
Travel towel/home-made tenugui, soap in draw-cord pouch, razor(s), container of shampoo, microfibre facecloth, mini-nailbrush, small mirror, spare comb. Very little else is needed.
With medical kits, it is easy to go for two many specialist items and overload your kit.
Insect repellant and sunscreen may be needed. EDC Pouch Contents
You will probably have several medical kits. I have a few items in my EDC pouch, and a more extensive kit with my travel bag. “Intermediate” kits are in various daysacs and the soft‑core bag. You should have a more comprehensive kit at home, in your car, truck, boat, aircraft etc.
Returning to the toilet roll(s).
Alcohol hand sanitizer is not the magical panacea that some people think. It is, however, a useful item to keep with your toilet roll(s).
You will also need some means to dig a cat‑hole.
This brings us to the theme of tools.

Tools

In the preceding article on foundation survival kits, I recommended the acquisition of a knife with “a full-tang fixed blade that is single-edged and not less than seven inches/18 cm”.
Knives and other tools are heavy, and can be very expensive. It is very important to have a realistic understanding of what you need.
You will see certain survival experts claiming that you do not need a big blade. Buy the little (larger profit margin) knife they use, available from the website… They fail to mention they have an axe with their pack, or a full film crew to support them.
In a survival scenario, the primary role of your knife is efficient shelter and fire construction and the ability to easily work any available materials for these purposes. You need a knife that is an effective multi‑purpose wood‑working tool.
Hence, my primary choice is a kukri.
If on a budget, machetes and billhooks will often do the job as well as any expensive custom knife.
A big knife can be handy when butchering large game, although in a survival situation you are more likely to be living on plants, small game and fish. To supplement my kukri, I carry a fixed-blade Mora knife.
Swiss Army Ranger
Another useful acquisition is a good pocket tool such as a Swiss Army knife. This forms part of your EDC, and may be the only tool you have when you really need one.
You will also need the means to resharpen your tools.

Digging

Digging tools need deeper consideration than they are sometimes accorded.
Hopefully the survivor will not have to be digging foxholes and bomb-proof dugouts.
More likely reasons to dig include:
• Edible roots and other foods
• Catholes and deeper latrines
• Disposal of biodegradable waste.
• Fire pits and trenches
• Pit traps
• Drainage gutters to keep water flooding your campsite: About 20 cm deep and as wide as your shelter
Indian well: Half a metre deep and wide
• Survival stills: About a metre across and nearly that deep. Will probably need two per person.
• Bank‑bunk/Den/Emergency dugout: A shelf to hold a sleeper, dug into the leeward side of a hill or bank. About two metres long, one wide and two thirds deep.
• Various types of snow shelter: Either digging down into snow or building a wall against the wind. When abundant fuel is available, try melting a hole down into the snow rather than digging it out.
Minor digging tasks may be achieved with a digging stick, throwing stick, tent peg, screwdriver etc.
Lightweight trowels are sold for campers and backpackers. Generally, these are either plastic or a high-tech material with a high price tag.
If on a budget, check out the trowels in the gardening centre before the camping store. The toy department is also worth a look, since beach and gardening sets for children are sometimes found.
hori-hori
My digging implement of choice is a hori‑hori. This is compact and relatively light, yet strong and versatile.
Many of the digging tasks listed can be performed with a hori‑hori. The larger excavations are possible in an emergency if you are methodical. For example, with the bank‑bunk, use gravity to your advantage so clods of earth levered out will drop away rather than need to be lifted.
A hori‑hori is a good choice for light and emergency digging. In certain terrain, situations or seasons, larger excavations are more likely.
Trifold Entrenching Tool
Trifold entrenching tools are probably the best off-the-shelf option for deliberate digging in terms of cost, utility and bulk/mass. Sometimes a hoe/mattock is a more useful digging implement than a shovel/spade. Buy a tool where the head can be set at an angle. Some models include a pick‑blade too.
Although used by the military, these folding tools should not be expected to be as sturdy as larger and/or one-piece tools, so use them accordingly.
For deliberate winter travel, lightweight snow shovels are worth considering. These may be aluminium or plastic, and some will disassemble or are telescopic for easier carrying.
Snow shovels are not much use for digging in hard earth, but can move large volumes of snow or leaf-litter. Items such as slabs of wood, skis, snowshoes, mess tins and frying pans may be used to move loose snow.
Knives with long blades can be handy for cutting snow blocks, although some arctic travellers carry crosscut saws from the hardware store for this purpose. These are useful for wood too. They are not as compact as camping saws, but a fraction of the cost. With a covered blade, such a saw may be slipped down the side of a rucksac’s main compartment,
If you live somewhere that is wooded and often cold, an axe such as a three‑quarter or Hudson Bay style may be a wise investment.
In an emergency, you may have to get out or into a location in a hurry. The crowbar may be a very useful addition to your kit.
Crowbars are very reasonably priced.
Wrap the shank in electrical tape to insulate your hands when it is cold. This also provides a source of tape for repairs.
A crow bar may be used like a digging stick or pick to break up hard earth.
For those with far bigger budgets than mine, there are titanium crowbars.
A screwdriver should be carried with your tent pegs. This may help in both inserting and extracting pegs. It is also a potential prying and digging implement.
Like the character in my novel, you will find such a screwdriver may be used for a variety of useful purposes.
Cordage may be considered to come under the umbrella of tools. Invest in a reel of suitably coloured paracord or similar.
In an emergency, some individuals may attempt to steal your food or equipment, or prey on you for other reasons. To ignore this as a potential possibility is to neglect the hard lessons of several thousand years of human history.
Many of the tools already discussed have potential as means of self-defence.
Since the publication of my book “Survival Weapons”, I have been asked which firearm an individual should consider purchasing first? Should it be a shotgun, or the .22 rifle?
Your first weapon should be compact or sub-compact semi-automatic combat handgun. It may be carried in situations where a rifle or shotgun might draw unwelcome reactions. It may be used to defend both your home and your person. In extremis, such a firearm may be used to hunt small and medium game in the absence of a weapon more suitable.

Sleeping

We spend about a third of our lives sleeping. Our performance when awake is often influenced by how well we slept. Sleeping gear is an important component of your emergency kit and in keeping yourself hale and hearty.
Man in Poncho0liner
In the original article, this requirement was met and represented by a poncho-liner or blanket.
Poncho-liners, as they are issued, are mainly intended as bedding. See my previous blog on simple measures that increase the utility of your poncho-liner as a garment.
A silver surivival blanket, or a more robust all-weather blanket, may be combined with a poncho-liner and pomcho for extra warmth..

Kip Mats

Once you have a poncho-liner, the second item on your sleeping wish‑list should be a kip mat.
Quite simply, “ground chill can kill!”
A kip mat is primarily insulation rather than cushioning.
Shop around, you can sometimes find a better deal on items marketed as exercise, yoga or gym mats. The main problem seems to be finding them in neutral or natural colours.
Some folks claim the black ones are inherently warmer, while some mats are offered with a reflective foil coating. No one seems to offer a foil‑coated black foam mat!
Naturally found materials such as grass, bracken, hay, pine boughs etc can insulate you from ground chill. Use your kip mat over the top of these. It will protect you from any damp materials.
Even when you can find one in a useful colour, it will be monochrome and of a regular shape. Kip mats are light but bulky. If you have to carry one on the outside of your pack, buy or make a suitable camouflage stuff sack. Fittings may be added to this so it attaches more securely to the outside of your pack.
You can roll a kip mat up in a camouflage bivi-bag, although potentially having a bivi-bag on the outside of a pack increases the chance of it being damaged and losing water resistance.
You can trim the corners of a mat into a more “mummy” shape if you wish, but this is not going to make much difference in mass and bulk. If you prefer your kip mat inside your bivi-bag, it may fit better if you shape it.

Sleeping Bag Liner

Your next sleeping acquisition should be a sleeping bag liner. Clean, dry insulation works best. A sleeping bag liner provides a little extra warmth, but its main advantage is that it keeps your bedding clean.
I have talked about sleeping bag liners before, so will direct you to that article. If your budget won’t allow you to buy your sleeping bags for a while, you might consider the warmer examples such as pile liners.
If personal security is an issue, you may need to sleep clothed and in your boots. Wearing a pair of sandbags over your boots saves your sleeping system from damage and dirt.

Sleeping Bags

Yes, I did say sleeping bags (plural)!
The poncho-liner was designed for sleeping at temperatures of above 10°C.
If your breath is fogging, you will need to make more elaborate sleeping arrangements, such as more ground insulation and a better insulated shelter.
Your sleeping gear will most probably acquire some sleeping bags. Sleeping bags are another topic I have addressed elsewhere.
Rather than buying a super‑duper arctic mountain‑rated bag, your money will be better invested in a one‑to‑two season and a two‑to‑three season bag.
Since we are considering items for your bug‑out bag, sleeping bags should be of mummy configuration for lower bulk and better performance.
Some folks prefer zipless. Personally, I find a zip offers more versatility with respect to comfort and ventilation. Ensure your choice, if zipped, has a two-way zip so that you may vent the foot area.
When you own two bags as suggested, you may use either or both together as local conditions dictate.
Your liner will add a little more warmth, and keep your bags clean and warm for longer.
Your poncho-liner will continue to see service as a supplement to your sleeping bags, or on its own in hot conditions.

Mosquito Nets

In many regions a mosquito net for sleeping under is a prudent investment. Working out how to suspend it may be a challenge you don’t need at the end of a long day, so look into free‑standing variants.

Shelter

Rain-Poncho

The rain‑poncho represents the theme of “cover”, which is appropriate since the rain‑poncho is both a garment and a means of shelter.
I have written elsewhere on the topic of selecting clothing for your “bug‑out outfit”, so I will concentrate on the topic of shelter.
Pocho Shelters
Your poncho probably came with a stuff‑sack. If it did, to this add two three‑metre lengths of paracord or similar. These will prove useful when you rig your poncho as a shelter.
A pair of bungee cords is quicker but less versatile, so may be added later.
If it is particularly windy or cold. one of these cords may be used as a belt around your poncho. The other may be used around your poncho‑liner.
A rain‑poncho and cord is not a complete shelter. You will also need some pegs or stakes. In extremis, your knife lets you carve them from sticks.
There are a number of ways to do without pegs, or for use when pegs won’t hold. I will deal with those some other day.
To your shelter kit add a small bag of pegs. Most shelters you can construct with a poncho or basha need four to six.
Add your screwdriver to this bag. This may be used for covert pegging, or as a spare peg. The screwdriver may also be used as a “T‑handle” to pull pegs up again.
Many of the shelters you may construct with a poncho require some means of support.
You cannot rely on convenient trees or even branches always being present.
Hiking/ski poles and bicycle frames have been used instead.
In addition to the above, your kit should also include a couple of tent poles, each with an extended or assembled length of about one metre.
The rain‑poncho “hooch” is a very basic form of shelter.
It is relatively low cost, even more so if you have ponchos issued to you.
Some servicemen carry three or four ponchos: one for wear, one or two for shelter and another as a groundsheet.

Bashas

A common upgrade is the “basha sheet”, which is a waterproof sheet of around 1.7 by 2.5 metres. It is similar to a lightweight tarp, although tarps tend to be three to four metres square. You will still need the rain‑poncho as rainwear.
In some previous posts, we saw how the American Civil War soldier used his gum-blanket as a groundcloth, shelter-cloth and rain protection. The basha is probably the closest modern equivalent.
Most basha sheets encountered these days have a camouflage print. However, the scale of the print is such they tend to show as a regular pattern.
A poncho/basha/tarp shelter may be improved by rigging two canopies, one below the other.
The inner canopy may be another poncho, a space blanket or even a suitably large non-waterproof cloth.
The double canopy retains more heat in cold conditions. It also insulates the occupant from the heat of the sun in the desert.
In the latter situation, the outer canopy may be a space blanket or similar reflective item. This also makes your shelter highly visible, which may or may not be desired.
This brings me to the topic of security.
One of the reasons the infantry use ponchos or bashas where possible is they give better situational awareness. They are also easier to vacate in an emergency.

Tents

A purpose‑designed tent may be warmer than a poncho/basha hooch, but also may make you more vulnerable to two‑legged predators.
This is something to think about when considering what form of shelter to include in your emergency or outdoor kit.
If you do opt for a tent, make sure that you buy a design that allows you to pitch the flysheet (outer) first and take it down last. Do not let any salesman con you that “flysheet pitches last” is an advantage. I have put up and taken down enough tents in the rain to know better!
When you buy a tent, the fly and inner probably packed in the same bag. Buy another bag and pack them separately. These bags should be distinct so that you know if you are reaching for the inner or the fly.
Avoid single layer tents unless they are made of a material that is both waterproof and breathable, such as Gore-tex. The latter are usually either bivi-bags or one‑man tube tents.
Single layer tents made from other synthetic materials either have condensation problems or let the rain in.
Single layer tents made from canvas/cotton duck etc are better, but tend to be heavy.
If you do opt for a tube‑tent or bivi‑bag. you will probably need a poncho or basha as well to give you a sheltered space you can dress or cook in.

Groundsheets

While not essential, a groundsheet will help protect the bottom of your tent inner. It may make the interior of a hooch more pleasant too.
If you carry your bedding items on the outside of your pack, the groundsheet may be used as an abrasion and water-resistant cover .
A groundsheet for a tent should be no bigger than the tent’s floor. Any material outside this area will channel water underneath. Similarly, a groundsheet for a hooch should be no bigger than the sheltered area.
Currently, several sources are offering cheaply-priced foil-coated sheets that have interesting potential as groundsheets. During the day, these could be staked out as reflector panels to attract attention. The sheets of silver material sold as reflectors behind radiators may also have potential.
These could be combined with a sheet of waterproof, puncture resistant material.
I have, on occassion, used my all-weather blanket as a groundcloth and insulation. When the cheap tent I was in started leaking in the alpine rain, I flipped the extra width over myself and stayed dry for the night.

Bivi-Bags

A bivi-bag may be thought of as a raincoat for your sleeping bag, or a one-man tent without the poles.
Being a single waterproof layer, they need to be of a breathable material such as Gore-tex, which ups their price. Gore-tex items tend to have a finite life until they stop keeping water out.
Bivi-bags are useful when you lack a kip mat or groundsheet to keep the damp out. They may be combined with shelters such as bashas and ponchos.
The bivi-bag provides a little extra insulation, so in warm weather may be used on its own or with a poncho-liner. In very cold weather it adds an extra layer of insulating air.
When inside the rucksack, a bivi-bag may be used as a water-resistant bag to store your sleeping system in. This puts your sleeping system in its own bag, rather than at the bottom of a rucksack-liner with all your other gear.

Conclusion

In this article I have built upon the foundation introduced in my blog on Foundation Survival Kits.
Some of these requirements may be easily met, with very little outlay.
In other cases, I hope this discussion has helped you prioritize your acquisitions.
There are a number of sundry or related topics, but these I will save for another day.

Adding a Pin to a Swiss Army Knife

The tools on a Swiss Army Knife sometimes end up performing tasks you never imagined!
A few months back I went to unlock my front door, only to have the entire barrel of the lock detach and come away with the key! The metal file/saw proved to be ideal for reaching to the back of the lock and turning the bolt.
My girlfriend’s son had asked me why I always carry my SAK. Exactly for times like the above!

The Early Years

For the first few years of my early adulthood I carried a Chinese-made version of a Swiss Army Knife. I vaguely recall there were actually two, although I do not recall why I had to replace the first. To be fair, these were quite nice knives, with a good assortment of tools. The only problem I actually recall is a time when the corkscrew straightened out as I attempted to open a bottle of wine.
Back in those days, they were all I could afford, and they served well.
Once I had some money, I invested in a genuine Victorinox Swiss Army Knife (aka SAK).

Victorinox Champion

The model I selected was called the “Champion”, not to be confused with the “SwissChamp” that had become available a few years previously.
The longer named Champion was less bulky than the Champ, lacking the pliers.
Swiss Army Champion
The seven-layer Champion was about the ideal maximum size for a SAK, and had a really useful selection of tools.
Sadly, my Champion was lost in an unfortunate chain of events that do not need to be told here. Even worse, the Champion had been discontinued, so I could not buy a replacement.
There was no ebay back then, so little chance of locating a second-hand one.
All the features of a Champion

Rise of the Ranger

As a replacement of the Champion, I selected a Ranger model. The most obvious difference between the two was the Ranger lacked a magnifying glass, fish scaler and Phillips screwdriver:
Swiss Army Ranger
• The Phillips screwdriver had proved useful at times.
• I don’t recall ever using the fish scaler/hook disgorger, at least not for its intended purpose.
• I didn’t make much used of the magnifier either, although now that I am older and more decrepit, I suspect it might prove more useful.
As an aside, the magnifying glass on the Champion was very cleverly thought out. Its focal length was the same as the magnifying glasses’ height. In other words, if you placed your knife on a map, the detail under the magnifying glass would be in focus. This may have been the case for other models that had the magnifying glass.
I wonder if the same applies to the newer pattern of magnifier?
Since I wear glasses, an early addition I made to both the Champion and the later Ranger was to add the mini-screwdriver that fits into the corkscrew.
Originally this tool was only included with the SwissChamp. They were sold as spares, however, so I acquired one.
This has proved very useful over the years, often coming to the rescue of companions rather than myself. Half a lifetime ago I repaired the glasses of a grateful Swedish beauty in old Jerusalem.
Corkscrew Mini-tools
Victorinox now offer three alternate tools, each with a different coloured end.
I have carried the Ranger for many decades now.
The lack of Phillips screwdriver is compensated for by the Leatherman Squirt mini-tool I also carry. If you are in the market for a medium-size (91mm) model SAK, the Ranger must be one of the best options.
The Huntsman model is a good choice, but I have often found uses for the file/metal saw of the Ranger.

Swiss Army Knife Wiki

Recently I came across the Swiss Army Knife Wiki. This site is worth a look around.
Some interesting information on how to use the various tools, and some applications for them you may not have known.
My Ranger had a Phillips screwdriver all along and I never knew! I discovered that the tip of the can-opener is actually intended for use with Phillips screws as well as slot.
The tip of the file/metal saw can also be used on some Phillips or Pozidriv screws.

Adding a Pin to a SAK

The original reason I have been thinking about Swiss Army Knives recently is that I came across a blog post discussing the pin carried in the handle scales.
Below is a video on possible uses for “needles” [sic pins]. The channel has many other videos on various features of Swiss Army Knives.


Even before I watched the above video, I was thinking about adding a pin to my Ranger.
I own a number of very fine drill bits, so creating a channel for a pin would not be too difficult. I could probably add a pair.
I have lots of cheap pins. I decided to try and find the pins actually used, since they were probably better quality and the head looked a little wider.
A number of ebay vendors offered replacement pins for Swiss Army Knives.
The one I chose got my money since they offered another idea. Included with the five pins was a small magnet.
This magnet was sized to fit in the can-opener. With such a magnet, a pin could be magnetized as a compass needle.
The bits arrived this morning.

Fitting the Magnet and Pin

The 5.8mm magnet was a perfect fit for the can-opener.
The vendor included the advice that the tool next to the can-opener usually needs to be opened before closing the can-opener with the magnet stored in it.
If this is not so, the magnet tends to pull out of position, attracted by the neighboring steel.
Although stainless steel, the blades of a Swiss Army Knife are magnetic.
Magnet in Can-Opener
Finding a drill bit small enough for the pin was not a problem. Problem was most were too short to drill a channel as long as the pin.
The other problem was my Ranger has solid scales. It lacks the air-spaces found on some newer and alternate scales.
Drilling a channel deep enough and straight enough proved problematic, and inevitably the very fine drill curved and the channel exited on the inner side of scale. This actually proved to be fortuitous, allowing me to file a notch on the inner side for end of the pin to rest in.
I settled for adding just one pin for now.
Most of the alternate positions for a pin are obstructed by the rivets the scales snap on to.
Ranger Knife Modified
My Ranger with pin added (blue arrow) and notches on scale (green arrows). If the balloon goes up, I am ready!

Other Modifications

Incidentally, the back scale of my Ranger has two additional non-standard features.
One is a chip, where an idiot friend used my knife as a bottle-opener without using the bottle-opener!
I could fix this damage, but it is a useful reminder to be more cautious of whom I trust.
More useful are a series of three notches. The second is five millimetres from the first, the third 57 mm for the first.
The first and third notch are used to draw a circle of 57 mm radius. The first and second are used to mark the circumference in five millimetre increments. Each millimetre of the circumference closely approximates one degree. Such a compass face can be used with various improvised modes of navigation.
Another addition I have made is to add a needle and thread.
Take about a metre of invisible thread and pass one end through the eye of a needle. Tie the ends together and then wrap the thread around the needle.
Push the threade-wrapped needle down beneath the saw blade. It should be snug enough that it will not drop out if you invert the knife with the saw open.
I used the metal saw rather than the woodsaw, since this is likely to see less use.
While you are at it, wax your woodsaw.

Pec-Knives and the Gerber Strongarm

Pec-Knives

The pectoral position is a very useful position to carry a knife. It is accessible with either hand, and if the wearer is seated or prone. It can be readily utilized to cut a jammed seat harness, or when rolling on the floor with an aggressor.
This topic came up in one of my discussions on soldier’s load. Modern servicemen have a lot of gear to carry, and many do not believe carrying multiple knives is warranted. If you are going to carry a single fixed blade knife, then the weak-side pectoral position is a good place to place it. This influences the form of the “pec-knife”. Pec-knives are discussed in “Survival Weapons”, and their use in “Crash Combat”. The more general discussion of knife use for defence in “Attack, Avoid, Survive” are also relevant.
You sometimes see quite large knives carried in this position, but for most of us an overall length of less than eleven inches is more practical. There is a wide choice of fixed blade knives in this size range. Harder is finding a knife of sufficient thickness and robustness. If this is going to be a soldier’s primary blade then it must stand up to some rough treatment.

Gerber Strongarm

A few weeks back I encountered the Gerber Strongarm. This just seemed to shout “I will be a great pec-knife!” Just before Christmas I got an email telling me the variant I wanted was back in stock. Money was short, but I had had a rotten day and a few minutes before midnight I gave into temptation and ordered a Strongarm. It helped that the price listed was about 30% less than most other stockists! Would you believe it? I looked the next day and the price had jumped a big chunk. I had ordered just in time! A few days later the Gerber Strongarm arrived. I wish I had had the money for another, but as it is I may run out before the end of January. Buy books please, people!

The Sheath and Extras

An important component of a potential pec-knife is the sheath. This mode of carry is most convenient with the knife inverted and the pommel downwards. Obviously it is necessary that the knife is fully secure in this position, but still capable of being easily drawn when needed in a hurry. The sheath of the Stongarm has a large clip that engages a depression on the hilt. Note that this releases with an audible click, which may affect your tactics in some scenarios. In addition to the clip, the smaller-width hanging strap has a retention strap with a popper. The latter feature is one of the few I have issue with. This is a little tight, the slight increase in grip width my lanyard has added making it sometimes fiddly to close. The length of strap past the popper is also on the short side, and may be difficult to pull on if wearing some gloves. It may be necessary to sew an extension onto this part.
An important feature of this sheath is that it is ambidextrous, so the knife can be inserted securely with the edge either to the left or right. This is useful for a pec-knife, it being considered to be prudent to carry your knife with the main edge outwards, away from your throat.
A couple of accessories are included in the box. I have already mentioned that the smaller-width belt hanger has the retention strap. This affixes to the sheath by a strap and popper. A larger width belt hanger can be attached to the smaller by poppers. Both belt hanging loops have poppers, making the easy to detach or attach without rethreading a belt. A device that allows the sheath to be mounted horizontally is included, as is a device allowing easy attachment of the sheath to MOLLE/ RALS systems.

The Knife

The knife itself comes with either a semi-serrated or plain edge, and is available in either black or a more practical coyote brown shade. The blade is 4.8 inches long, and 3/16th thick. Overall length is 9.8 inches and weight is given as 7.9 oz. Blade material is 420HC stainless steel with a dark grey coating. Grip is a rubber coating over glass-reinforced nylon. There is a resemblance to Gerber’s LMF II knife. The LMF II is heavier (c.12 oz) and costs more. I have not handled a LMF II, but the Strongarm seems a better choice for the pec-knife role.
The butt of the Strongarm ends in a blunt triangular point that might serve for applications such as window breaking. This feature is thoughtfully provided with a lanyard hole. I know I have said this before (yesterday actually!) but it really is surprising how many expensive knives are not provided with provision for a lanyard or other features to reduce the chances of loss.

Making a Chest Rig

There are plenty of good reviews of the Strongarm out there, so I will concentrate on specifics of rigging it as a pec-knife. This is actually very simple. Obviously, you can mount the sheath directly on your webbing, but what if you are not wearing such? The Strongarm is potentially a very useful knife, and you may want it when you are not in full tactical gear. I have seen the Strongarm described as a cross-over” knife, good for urban and wilderness.

Take about two metres of paracord. I know frugality is a virtue, but it is prudent to have a little too much rather than start again. The Strongarm sheath has a number of “screwholes” down each side. Pass one end of your paracord through a hole near the sheath mouth, and the other through a hole on the opposite side, second from the end. This should be made clear from the photos. Experiment with what arrangement suits you personally. Pull both ends of paracord so the middle makes a snug length across the front of the sheath. Now take both lengths, hold them together and tie a single knot in both. This can be an overhand knot but a figure-eight may be more comfortable when worn. You should have created a large loop with the knife sheath threaded on it. This loop should be large enough to pass your weak-side arm through, the knot sitting somewhere between your shoulder-blades. Take the long, free ends and form them into a second loop using the knot I call a “slip-bend” in my free book on knots. Place your other arm through this loop and tighten it by sliding the two parts of the slip-bend apart. The Strongarm sheath should be hanging just before your weak-side armpit. If you have the small-width belt hanger still attached this may be used to anchor the sheath to a belt, if you wish. Note the snap-link, added by a magnus-hitch. The lanyard can be attached to this when greater security is wanted. It also proves useful for holding other items. I later relocated the snap-link to below the sheath, where it helps keep it in position.
A chest-rig for a knife can cost tens or hundreds of dollars. This one is simple, lightweight, comfortable and costs just a couple of metres of paracord. If you like this, throw some of the money you have saved this way!

New Machete Grip

Surprisingly, machetes have featured infrequently in this blog. Possibly this is because much of what could have been said is already covered in “Survival Weapons” and “Crash Combat”.
One of the virtues of machetes is that they are mass-produced in their thousands, allowing you to acquire a reasonable quality tool for a very modest outlay. Sometimes the sheath costs more than the knife!
Some auction sites that no longer sell “knives and bayonets” still sell machetes.
A typical machete may be a fraction of the price of a smaller survival knife, yet prove more capable and more useful.
In addition to new items, you may find some bargains second-hand or army surplus.
Certainly, there are machetes being sold for hundreds of dollars, but it is unlikely that ten times the outlay will get you a ten-times better tool.
The price of machetes is such that you may find yourself owning several, and distributing them among various kits and caches. You may have one in your garden shed, another with your bug-out bag, and one with your vehicle, plane and/or boat.
If you are a bit of a kit tinkerer, this gives you an excuse to try out a variety of models without wasting large amounts of money.

Adding a Barong Handle

I have spent the last couple of days fitting one of my machetes with a new grip. The new grip is modelled on that of a couple of barongs that I have.
Machetes sometimes attempt to escape their user! You might cut at a springy branch placed under tension by other growth. Such an event can knock a machete right out of the user’s hand and send it flying into the brush.
It is rather surprising that more machetes do not feature retention features such as knuckle bows and wrist loops. Many models don’t even have a hole in the grip for fitting the latter!
The barong-style handle is functional as well as cosmetic. The bird’s head shape facilitates both retention and manipulation.
My grip is made from teak, which once served as a chunk of laboratory bench top.
The grip was shaped with a variety of hand-tools, with the occasional use of a Dremel-tool and an electric drill.
Once the sanding was complete, it was treated with several applications of linseed oil.
The metal collar was made from a strip of soda can.
Just above the machete you can see one of the original handle halves.
The only modification made to the blade was one corner of the tang was reduced and rounded.
Flip-side view: Some dust still in need of cleaning off.
I changed the cord for a longer piece with an extra knot, to allow use as both a wrist loop and a thumb loop.
The grip part could be slimmer, but I err on the side of caution when carving.

Sharpening a Machete

Currently, I am sharpening this machete up, and it now has a reasonable edge on it.
Most newly purchased machetes need some sharpening.
You will be tempted to try sharpening it with a Dremel or bench grinder, but it is possible to overdo this.
Machetes are made of softer metal than most smaller knives, and do not need a fine edge. The “micro-serrations” of the edge actually help the machete bite on vegetation.
This means all you really need is a medium-sized “bastard” file. A round file is useful for major work on tools with a concave edge, such as kukris and billhooks.
In the field, you can maintain the machete edge with your usual sharpening tools. My EDC includes a diamond-impregnated card, and my kukri has a chakmak and small stone with it.
If planning a trip where you expect your machete to see lots of use, it is worth packing a file in your camp gear.
Hold the file at an angle of around 22.5 degrees (for example) to the blade flat and push away from the spine.
The noise the file makes on the steel will give you clues as to which parts of the edge need more work. Sharpening sometimes involves touch, sound, and/or sight.
Half a right angle is 45 degrees and 22.5 is half this again. Fold the corner of a piece of paper twice and use this to check your angle.
I have been sharpening with the machete across my knees, edge away from me.
You could probably make a rig with a couple of supports at 22.5 degrees. The width, flatness and relatively straight edge of a machete favour this arrangement.
With the machete resting on the ramps, edge up, a file held horizontally will be at the correct angle.
Now I have an edge at the correct angle it is easy to file either side while holding the blade vertically.

Survival Kits: Bringing It All Together

Today I am going to try and bring together some of my ideas regarding survival kit and selection of contents. When possible, I try to approach topics from a different perspective to that echoed on most websites.
Regular readers may know that I have my reservations about the “little tin of gizmos”. Thinking that you are covered because you have a couple of band-aids and a couple of loose fishing hooks and swivels is a recipe for disaster.
Survival kit may exist on several levels. On your person you will have your skin-level EDC. Most of mine is in the pockets of my trousers, although some items are on my trouser belt or key-ring. If you are carrying a bag, it is prudent to have some additional items in your bag. You consume the items in your bag in preference to your skin-level items. Military personnel often have an intermediate level in their webbing load-bearing equipment. Ideally this should only hold ammo, weapons, some water and immediate first aid items but the tendency to add additional gear is common. A larger pack or vehicle may provide higher levels of survival gear. One should always plan for the contingency that one may get separated from bags or vehicles. This is why your skin-level gear is important.
My current planning list looks like this:
Seven Tools of EDC
Hat, Towel, Rope
Medical, Writing, Fire, Knife
Foundation Survival Kit
Blanket, Fire, Knife
Poncho, Water, Toilet Paper, Canteen Cup
Travelling Kit
Navigation, Signalling, Illumination
Washing, Repairs, Food,
Documentation, Money, Clothing, Armament
The item names are memory aids and should be taken generically rather than specifically. “Knife” represents other tools, “blanket” represents sleeping bags and related items and so on.
The Seven Tools of EDC
The Seven Tools of EDC were inspired by the roguku or Six Tools of Travelling. I remember these as three flexible things (hat, towel and rope), three multi-part things (medical kit, fire kit and writing kit) and a knife.
Hat” represents other protective clothing, such as gloves, goggles and sun-glasses. At “skin-level” this will be whatever headgear and other items suits the current or expected weather. If I am taking a bag I will probably have two hats. One will be to protect from the sun and keep the rain off my glasses, probably a boonie hat. The other will be a warm hat such as a watch cap or headover. If it is really cold spare gloves and headover are a prudent precaution.
Towel” in this context is a multi-purpose piece of cloth. At skin-level this is a bandanna in my pocket but recently I have also been wearing a shemagh. If I lose or did not bring my hat these can serve as head coverings. Any bag I carry usually has a spare bandanna and/or shemagh in it. In colder conditions the shemagh is replaced or supplemented by a woollen or acrylic scarf.
Rope” for the ninja may have meant a grappling hook and rope. For me this reminds me to carry some cordage. At skin-level this is a couple of armspans of paracord, a hank of string, a container of dental floss and a retaining cord for my glasses. Packs contain longer lengths of paracord. If heading for the deep wilderness I would have a toggle rope or the modern equivalent.
Medical Kit. On my person I have a small number of plasters, alcohol wipes and pain-killers, plus some personal medication. I have a more extensive medical kit I carry in daysacs, plus a bigger kit in my travelling bags. Medical also includes such items as insect repellent and sun cream. These are usually bag items but certain conditions may require a small supply to be carried on your person. Whenever possible items are consumed from the larger kits before the skin-level kit.
Writing represents communication and recording. In my pockets I carry a pen, pencil and two pieces of chalk (one light, one dark colour). Usually have a phone on my belt. Daysac may contain a notepad in a plastic bag. When on holiday I keep a journal.
Fire Kit. For everyday use this is simply a disposable lighter riding in the bottom of a pocket. I carry a plastic bag with a couple of tissues in, which could be used as tinder. If straying further afield I would add a container of tinder, fresnel lens and spare lighter to my pockets. Daysac has a couple of spare lighters and some candles.
Knife” represents tools and related hardware. My Swiss Army Knife goes nearly everywhere with me. I also have a Leatherman Squirt and pocket prybar on my person. A diamond impregnated metal card is carried for sharpening.
Foundation Survival Kit
The items on the Foundation Survival List are mainly bulkier “bag” items, with a couple of significant exceptions.
Blanket” represents sleeping items in general. It includes poncho-liners, sleeping bags, cloaks and long coats. These can keep you warm, even when not sleeping. This category is called “blanket” to remind us about the survival blanket, which is compact enough you can easily fit one or more in a trouser cargo pocket. They are reasonably priced so you can buy a dozen and stick spares in coat pockets and any bags you might carry. As well as keeping you warm, they can keep the rain off, spread out as a signalling panel, possibly even used as a heliograph. One is in the little medical pouch that carries most of my skin-level EDC. For decades now my daysac has carried the survival blanket’s larger cousin, an All-Weather Blanket.
Fire Kit. A fire kit was included in the original Foundation Kit list. It is repeated since the ability to create a fire is an important component of survival. Have a means of making fire on your person, and additional means in your bag. Consume the bag supplies before that on your person.
Knife. Another duplication, but repeated for much the same reason. In this context it can be read as “a bigger knife”. Useful as a pocket knife or muli-tool are, they can only get you so far. This category also reminds us to remember other, larger tools such as a crowbar or entrenching tool. Have a fixed-blade knife on your trouser belt. If you lose your pack, webbing or even your jacket or shirt you will still have a useful survival tool.
Poncho includes other forms of rain-proof clothing and shelter items such as tarps, tents, shelter halves, basha-sheets, groundsheets and so on. Any bag of sufficient size should include a means of rain protection.
Water represents a means to carry water, and the means to ensure that it is drinkable, such as water purification tablets. In rural areas a supply of water and purification tablets should be both on your person and in your pack. Consume the water in your pack before that on your person.
Toilet Paper. A roll of toilet paper in a waterproof bag is a prudent addition to any bag. A small bag with a couple of paper tissues rides in a cargo pocket of my trousers. A bag with additional tissues will be added if I am heading off the beaten track. As well as intended use, such tissues can be used for nosebleeds, nose-blowing and as tinder.
Canteen Cup. A metal canteen cup or similar small cooking vessel is a useful addition to the above items. Boiling water to sterilize it will conserve water-purification tablets. It can also be used to sterilize instruments or blades intended for medical uses. Even if you wear a water bottle on your person, the canteen cup is probably best carried as a pack it. The interior can be packed with some of the smaller items listed above.
There is a survival adage that says you cannot live three minutes without oxygen, three hours without shelter can kill you, you can last three days without water and three weeks without food. The Foundation Kit contains the essentials towards keeping you alive beyond three days.
Travelling Kit
What I have chosen to call the “Travelling Kit” are mainly “very useful” rather than essential. Food is obviously essential, but you can last several days or more without it.
Repairs. If away from home, a small repair kit is worth putting together. My compact little sewing kit has seen many uses over the years. This is supplemented by a couple of rucksac buckles, dental floss, a roll of electrical tape and a tube of superglue. A small screwdriver that fits in my Swiss Army Knife corkscrew has been used to repair several pairs of glasses. I have seen it suggested that a piece of glue stick of the type intended for hot glue guns may also be useful. You can even add a little repair capability to your skin-level kit. A small bag of safety pins can deal with tears and zipper problems. Around the pencil I have wrapped a length of electrical tape then bound two threaded needles to its sides.
Food includes food procurement and cooking means. Put together a small fishing kit, with some wire traces that can be used as snares in extremis. Assemble as much of the kit as is practical before hand. Sitting in the wind and rain as the light fades is no time to be tying on swivels! Add the fishing kit to your trouser pocket items if heading into the wilds. The food you carry should include some items that can be consumed without heating or rehydrating. Some boiled sweets/ hard candy is a useful addition to any daysac, giving a quick energy boost when it is needed.
Illumination. There are numerous small flashlights that are suitable for skin-level EDC. The little Photon lights can be added to a keyring, dogtag chain or whistle lanyard. A larger flashlight is a suitable addition to a daysac or larger pack. My daysac has a handcrank model in it.
Navigation. Personally, I have found a small compass a useful addition to my EDC. Even in town it is sometimes useful to know which direction is which. A number of guidebooks have information such as “…the hostel is to the northwest of the piazza”. If travelling away from civilization better maps and compass are recommended. GPS is nice, but you should plan for when it stops working. Without a compass there are other ways to determine direction, which is why these items are under “very useful” rather than essential. Worth repeating is that in most cases where rescue can reasonably be expected your chances of survival are better if you stay put rather than walking out.
Signalling. Signalling assumes there is somewhere out there to signal to. Flares are not much use if no one is likely to be in line of sight. Tell someone where you are going and when you will be overdue. Signalling overlaps with Illumination and Fire, and mobile phones have already been mentioned. Your skin-level kit should include a whistle. Mine is on my key-ring. A small heliograph is easily fabricated. The back of my phone is mirror-polished, so I would use this instead.
Washing. If you do any travelling you should put together a lightweight wash kit. How to put one together is detailed on another page. I prefer mesh bags over the more elaborate, heavier and more expensive wash bags.
Documentation. Travelling may require visa, permits, passports and other documentation. Make sure you have it all before any trip, and store in a waterproof bag. Make photocopies of important documents, such as your passport, and carry then separately to the originals. I prefer to carry some of these things on my person rather than in a bag.
Money. In some environments, one of your most useful tools. Includes credit, debit and ATM cards. Have information on what to do if you lose the latter. Don’t put all your eggs in one basket!
Clothing. How much spare clothing, its type and quantity will depend on trip duration and conditions. 
Armament. Carry if you can. The world is full of nasty people who will rob you or hurt you just because they can.

New Survival Tool: The Brick Hammer

Some time back I was reading a number of manuals written for the British Home Guard.
Fighting in an urban environment was a common theme.
Many of the authors drew from experience in the Spanish Civil War. They had learnt that urban terrain could negate an enemy’s advantages in air power and armour.
Urban operations was expected to be routine, rather than exceptional.
It is safer to be firing from loopholes rather than from windows, but I began to wonder about the practicalities of cutting a loophole in a brick or similar wall.
The Home Guardsmen probably would have had available the 1937 entrenching tool, which included a relatively stout pick. Troops with other designs of entrenching tool may be less capable.

A bit of research turned up the tool shown below.
This is sold as a “brick hammer”. I will confess, I have yet to try cutting loopholes with it. My landlord would probably object
This is potentially quite a useful survival tool.
The adze part can be used for digging, and should be more than adequate for such tasks as creating cat-holes or Indian Wells.
The hammer part can hammer things, such as tent pegs if stealth is not a requirement.
Shank and head are both steel, so the adze could also be used as a prying tool or crowbar.
If necessary, it can serve as a passable hand weapon or missile.
It could potentially be used as an anchor or for hooking.
The brick hammer is relatively compact and light (718 grams with tape and cord), and very reasonably priced.
For trips that are unlikely to require building foxholes, this may be all the entrenching tool you need.
In its original state, this particular brick hammer was polished steel and a black rubber handle.
I have given the metal parts some paint, although I expect this to wear off with use. The handle was covered by some self-adhering grip tape I had, and I have added a thong for retention.

Hori‑Hori for Survival

One of the many things that became apparent after the American Civil War was that the infantryman needed a means to quickly construct earthworks.

“Hardtack and Coffee” informs us that the quartermaster of the army had wagons of intrenching tools [sic] that were supposed to be supplied to units that needed them.

In practice, there was seldom time to send for these tools, and infantrymen resorted to digging with their tin plates or muckets.

As you can see, there were attempts to modify spike bayonets for the role.

One of the solutions offered after the war was the Rice trowel bayonet, which began to see trials in the late 1860s.

Available on-line is a document detailing the findings of the trails.

While a few officers expressed reservations, the opinion of the enlisted men and many other officers was overwhelmingly positive.

The document describes “rifle-proof” parapets being constructed in as little as nine minutes.

This would be impressive, even with larger modern tools.

The trowel bayonet was clearly superior to the improvised means the troops had been using before.

It also had sufficient size, heft and edge that it could be used to cut saplings and branches, something beyond the current spike bayonet.

Many believed the large, spear-like blade would make a better bayonet than the spike bayonet.

Breech-loading rifles were coming into service, and many were of the opinion that the bayonet might be becoming obsolete. If it wasn’t quite as good a bayonet as the weapon it replaced, this was tolerable and its greater utility made up for this.

The main objection to the trowel bayonet was that troops might be tempted to dig with it while it was mounted on the rifle. This was likely to bend the barrel, damage the muzzle or block the bore. (One reviewer does point out that the trowel was a less effective digging tool used in this way, so the practice will be rare. Someone was bound to try it, however).

Shortly after the introduction of the trowel bayonet it was replaced with a trowel knife. This probably had a better grip than the trowel bayonet, but its rounded tip gives it a less war-like appearance and possibly it was of less utility as a hand weapon. 

Bayonets continued to evolve, but along different lines.
The next step was the sword-bayonet, intended to serve as bayonet or hanger.
Some infantry had carried both bayonets and hangers. Napoleon’s guard around 1815 spring to mind as an example.
By the 1880s, most infantry had long since discarded the hanger, so effectively the sword bayonet was replacing an implement that was no longer carried. Nonetheless, many armies entered the 20th century with sword bayonets, and would be using them until the 1940s at least.
The idea of letting the infantry have their very own entrenching tools had taken root, however.
Infantry entrenching tools got bigger and more sophisticated until they reached the form we know today.
As has been discussed before on this blog, some of these tools are overkill for the non-military user.
It is a hygienic cathole, rather than atomic-proof foxhole, that we generally need.
There are little plastic trowels, of course, but these are not much use for anything else. The trowel bayonet suggests a relatively small digging tool can be a useful survival aid. Is there a modern equivalent?

Seeking to answer this took me to discover the hori‑hori.
In another blog I described how I had seen machetes used as jack of all trades by gardeners in Jamaica.
The hori‑hori is a similar device, but more compact. Not surprisingly, these are Japanese.
The ninja put a similar digging tool, the kunai, to various uses.
The hori‑hori were originally used for gathering wild foods, so technically are already survival tools. A variety of models of hori‑hori are available, but the one I have has a 7 inch blade, so more compact than the 10 by 4 inch blade of the original trowel bayonets.
One edge is serrated, the other can be used to chop or cut, or will be once I sharpen it. (The packaging says it comes “razor sharp”, which apparently means “unsharpened”.)
The blade is a broad spearpoint, with one side slightly concave, as suits its digging role.
Mine came with a nice condura sheath.
Unlike many survival knives, this is a tool the makers recommend that you can pry with.
Price is a bit more than a normal trowel, but this can be offset against the fact that many gardeners think they do not need many tools other than their hori‑hori.
On the other hand, compared to many survival knives and tools, the price is very reasonable.
Make sure that you do not buy a mini‑hori‑hori by mistake! Mine has a blade of 18 x 4.5 cm. I also recommend a stainless steel bladed example. The mirror finish on the blade may have applications for signaling.
The hori‑hori seems a pretty useful tool to have along on a trip or stored in an emergency kit. A useful backup or replacement for a survival knife.
