Knives You Need: Part Two, Swiss Army Knives

“Til I woke up dry beneath the African sky
Just me and my Swiss Army knife”
“Last Mango in Paris”, Jimmy Buffet
I had originally planned to make “Knives You Need” a two‑part series.
I have now had second thoughts.
The second part was going to address the topic of field knives. Much of it would have repeated ground already covered in other previous articles.
Instead, I have decided to take a slightly different angle and have decided to break this topic into smaller, bite‑sized pieces.
Many of you reading this may have spent good money getting yourself a survival knife. Good tools are important, you will get no argument from me on this point.
However, unless you spend all of your time in the great outdoors, the odds are that when you really need a tool, that survival knife will be back at home or in your car rather than on your person.
What is more, the tool you actually may need may not actually be a knife.
If you are willing to spend hundreds of dollars on a survival knife, is it not sensible to invest a little in the tools you are most likely to carry with you every day?
It is no secret I am a big Swiss Army Knife (SAK) fan.
Multi-pliers and lock knives will be covered at a later date.
Today, I want to cover some of the points I did not make in my previous article on SAKs.

Safety First and Always

Critics of the Swiss Army Knife point out that the blades lack a locking mechanism and potentially may close on the fingers of the user.
In practice, I have seldom had this happen. Perhaps penknife users are more cautious due to the lack of locking mechanism?
Mechanisms fail, so a lockknife that is mistakenly used like a fixed blade may be a greater potential risk.
There are several websites that give advice on safely handling and using penknives. Many of these are written for scouts, but many older users would probably benefit from putting these ideas into practice.
I recently read of someone who did have a blade close on them. They accidentally hit the back of the blade against a nearby wall.
This might have been avoided if the user had taken the precaution of extending an arm and checking for clearance around themselves before starting at task.
This is a prudent procedure for any tool use.
If using a long tool like an axe, hold it at full extension and check all around you. Do not forget to check for obstructions above and below you too.

The Penknife Grip

When using a folding knife, use what I call “the penknife grip”.
Safe way to hold folding knives.
Your four fingertips are pressed against one scale. The opposite scale is held by your thumb and themar eminence. This keeps your precious digits out of the way of the main blades. This is the way to hold your penknife when opening tools.
When you need to close a tool, hold the knife in the same way and place the palm of your other hand on the back of the open tool. Calmly and smoothly fold your hands together to close the tool.
Many actions can be performed with your knife held in the penknife grip, keeping you safe should a tool unexpectedly close.
Some tasks will require a grip with your fingers around the knife body. Ensure a solid object, such as what you are working on, obstructs the tool from closing and that any pressure is applied in the correct direction.
Never use force to compensate for a blunt tool!
Never cut towards a body part, including your own. This simple and sensible precaution is often neglected in Youtube videos!

Right Tool for the Job

The risk of injury may be reduced by using the right tool for a job.
The long knife blade and sawblades probably have the greatest potential for causing injury.
If you need to cut something, the short blade or the scissors may be more appropriate.
If you need to bore a hole, use the shorter blade or the reamer.
If you need to pry, use the can- or bottle-openers, or better still use a more appropriate tool that is not your penknife.
In the pouch I carry my penknife in, I also carry an eight centimetre-long flat pocket pry bar.

Classic SD

On my keyring, I have a 58mm Classic SD. It is handy for trimming my nails or other minor jobs that it is not worth getting the main Swiss Army Knife out for.
The Classic was donated by the lost property box. It originally had green cracked scales and was missing its tweezers.
A few years back, I treated myself to a new toothpick and tweezers, which had recently become available in green.
Recently, it occurred to me how shabby the cracked scales looked. I would need something that matched the green of the toothpick and tweezers.
I found a set of replacements at a tolerable price. What was more, the new scales were in luminous green.

The Classic has a small blade, a pair of scissors and a nail file. The tip of the nail file of the SD model is designed to act as a screwdriver. The screwdriver tip is still good for cleaning nails.
A friend showed me the 58mm Rambler, which has all the blades of the Classic SD plus an interesting combination tool with a cap‑lifter, Phillips screwdriver and wire‑stripper/bender as well. I might consider one of these if I ever need to replace my Classic SD.
Incidentally, SAK with Alox scales generally do not have tweezers and toothpick slots. I would recommend only considering models that have these useful tools.

91mm Swiss Army Knife Models

When it comes to “full-sized” (91mm) Swiss Army Knives, Victorinox currently offers 28 different models.
For general use, survival, emergencies or EDC, I would suggest one of the following models:

Spartan

As one might expect from the name, the Spartan is the most basic model of the 91mm Swiss Army Knives. Apparently it remains one of their best sellers.
It is a two‑layer knife, so you get a large and small knife blade, plus the can‑opener and the bottle‑opener. On the back is the reamer and the corkscrew.
The applications for the knife blades are fairly obvious. Quite large pieces of wood may be split or removed by using techniques such as batoning.
The knife blades are sharpened at an angle of 20 degrees.
The X-notch is useful for construction of rabbit stars.
The X-notch is an alternative to the square or log-cabin notch. It may be created by saw cuts or batoning a knife blade
Both the can-opener and the bottle-opener have applications that may not be immediately obvious.

Bottle‑Opener

The notch on the bottle‑opener/cap‑lifter works together with the cutting blade to serve as a wire-stripper. The notch may also be used as a wire‑bender or nail‑puller.
Various other parts of the bottle‑ and can‑opener or the keyring eyelet may be utilized bending wires or similar materials.
The tip of the bottle‑opener is a large (6 mm) slot screwdriver. This will fit in a socket heads adapter should you need another type of screw head. The screwdriver tip may also be used as a light prying tool.

Can‑Opener

The tip of the can‑opener is a small (3 mm) slot screwdriver. What is not often appreciated is that this part is also intended to work with Phillips screws too. The tip may also be used for light prying, such as opening stubborn pistachio nuts.
The hook part of the can opener may also be used to cut tape on boxes. Felix Immler has a video on how to turn this part into a more efficient hooked cutting tool.
This can-opener may also be used as an orange peeler or a billy lifter.
One of my favourite uses for this tool is that it can be used to carry a 5.7 mm magnet. The magnet is useful for picking up or holding secure small screws, or magnetizing a pin, tweezers or needle for navigation.

Corkscrew

My main use for the corkscrew is to carry the mini‑screwdriver. The mini‑screwdriver is an essential for anyone who wears spectacles or even sunglasses. Not all SAK come with the mini‑screwdriver. I very much recommend acquiring one.
Not surprisingly, all the SAKs I recommend have corkscrews so you can carry a mini‑screwdriver.
The mini‑screwdriver may be used as a tiny prying tool to pop the back off a watch and to remove the battery. It may be used to drive out small pins, and may be used this way when replacing the spring of the SAK scissors.
Imaginative other uses for the corkscrew include bending wire, untying knots, use as a drawing compass, rawplug retriever and as a parcel carrier for penknives that lack the multi‑purpose hook.
Cotton wool may be wrapped around the corkscrew to serve as a source of tinder, or it may be used to carry a supply of fishing line.
There are other alternate tools designed to fit in the corkscrew, including the Fireant, a tiny ferro‑rod. Larger diameter ferro‑rods may be cut down to fit within the corkscrew.
I have glasses, so carry the mini‑screwdriver.

Reamer

The reamer is another very versatile tool. It acts as an awl, a scraper, a seam‑ripper, wire‑stripper, wire‑bender and a threading tool.
The reamer is very useful for creating pilot holes for a drill bit or gimlet. It may be used to clean up or bevel a hole you have bored.
A bit of trivia: when your reamer needs resharpening, it should be sharpened at 48 degrees.

Compact and Climber

A friend of mine likes his Compact Swiss Army Knife. Unlike many Swiss Army Knives with only a few layers, the Compact includes the pen and mini‑screwdriver.
The Compact is a two‑layer knife like the Spartan but replaces the small blade with the scissors, and the reamer with the multi‑purpose hook. Instead of the cap‑lifter and can‑opener, there is a single “combo‑tool” that serves as a 6 mm screwdriver, can‑opener, cap‑lifter, wire‑stripper and wire‑bender.
Personally, I think the reamer is a “must‑have”.
The Climber is a three‑layer version of the Spartan, adding the hook and scissors and retaining the reamer and small blade.

Scissors

Keeping your toenails trimmed is an important part of looking after your feet (and socks). The Swiss Army scissors are excellent for such applications. Better than many purpose‑designed items!
The scissors are also surprisingly robust, being quite capable of cutting through soda cans and tin can walls to construct various items.
The scissors are probably the Swiss Army tool I have used the most, and I suspect I am not alone in that. I regard the scissors as a must‑have feature on a Swiss Army Knife.

Multi‑Purpose Hook

If I recall correctly, the multi‑purpose hook was once called the “parcel hook”, being intended to hook though the string of a heavy parcel or bundle of firewood and let you use your penknife as a handle.
The hook is rated for 90 kilos/200 lbs of load!
The hook is often underappreciated, since there are many other applications for this item. These include being used to untie a stubborn knot, twisting materials to make natural cordage or an eyelet in wire, lifting hot billies or their lids, pulling stuck zippers, as a pen holder, retrieving tent pegs, and tightening lacings.
Some hooks have a nail-filing surface on the back.
The hook may be used to store a 3 mm magnet.
Check out some of the videos on‑line for more applications.
There is even a modification to turn the hook into a groove carving tool. Worth considering if your penknife is a dedicated whittling tool. Putting a cutting edge on your hook may make it less effective at some of its other applications.
Trivia: The hook and scissors will be mounted on the same layer. If your knife has one tool, it will have the other too.

Huntsman

The Huntsman is another of Victorinox’s best sellers.
Effectively, it is the Climber with a woodsaw blade to create a four‑layer model.
A Huntsman will cost approximately twice what you might pay for a Spartan. Prices vary a lot, however, so shop around!
For “bushcraft” and “woodcraft” use, the Huntsman is a really good choice, having both the scissors and a wood saw.

Wood Saw

Many traps and other items you may wish to construct may require accurately cut parts.
The wood saw is also useful for scraping bark off, creating sawdust or shavings for tinder, descaling fish, and may be used as a striker for a ferro‑rod.
Trivia: The wood saw is one of the few commonly used SAK tools that lacks a nail‑nick

Ranger

My own model 91mm SAK is a five‑layer Ranger.
Oddly, the original scales of my Ranger have “Camping” and a tent logo. Several models of SAK other than the Camper have this decoration.
The Camper is the Climber with the wood saw in place of the scissors. I regard the scissors as a higher priority, hence I recommend the Climber or Compact in preference to the Camper.
Swiss Army Ranger
The Ranger is the Huntsman with the addition of the metal saw/file. It also has a chisel blade and a 2.5 mm fine screwdriver on the back.
A Ranger will cost approximately two and a half times what you might pay for a Spartan. As I have already said, prices vary a lot, so shop around!

Metal‑Saw/File

I once had to cut down the bolts on a rucksack frame since they were digging into my back, so I like having the metal saw/file.
The metal saw is better than the wood saw for cutting some plastics and for some wood‑cutting tasks.
It is also a good striker for a ferro-rod. Keep the saw still and pull the rod across the back.
The file may be used sharpening improvised fishing hooks.
The tip of the metal saw may be used as a Phillips screwdriver
Since the seven‑layer Champion was discontinued, the Ranger is as big a Swiss Army Knife as I care to consider carrying. I don't really want something over three centimetres thick!
I never found much use for the hook‑disgorger and descaler on the Champion.
I liked the Phillips screwdriver and magnifying glass. As I get older, I can find even more uses for the magnifier.
If Victorinox were to offer a six‑layer version of the Ranger (“Ranger Elite”?) with an inline Phillips and a magnifier, I might be tempted.
My Ranger has been with me several decades now. It will probably outlast me.
A couple of modifications have been made to my Ranger over the past few years:
One of the first things I did when I brought my Ranger was add a mini‑screwdriver to the corkscrew.
Later, I added a magnet to the can‑opener and fitted a pin to the scales.
A sewing needle, wrapped in invisible thread, has been placed under the metal saw.
The tweezers have been modified to be pointed. The tweezers with my Classic SD are unmodified, so between the two knives I have both a pointed and a standard configuration set of tweezers.
A distance of 5 mm and 57 mm is marked on the rear handle scale.
A safety pin has been added to the keyring.

New Scales!

I liked the new scales on my Classic SD so much, I went ahead and brought a matching set for my Ranger. I kid myself this will make it less likely to lose in Autumn.
Generally, I like my kit “low-key”. The SAK is an exception, since it is not really a tactical nor defensive item. It is, however, valuable in both replacement cost and in utility as a resource. Thus I like that the new scales make it easier to see and hopefully less likely to lose.
Check out this modification, however, since it may be applicable to other knives and tools. So might this idea!
These are “plus” scales, so have additional carrying places for a pin and an SAK pen. I drilled another well for a second pin.
As well as being luminous, the scales have some nice texturing for improved grip.
The larger 91mm scales were a bit harder to fit snugly compared to the 58mm for the Classsic SD. I had to use a vice.
Do not forget to pad the jaws so you do not damage your new scales!

Old Ranger with new luminous scales. Note magnet carried in can-opener.
Slots for the scale tools were very snug for both sizes of scale, making the tools difficult to remove. I used a circular needle file to create a small scallop underneath which solved the problem. Overdid it a little on the toothpick for the Ranger , but adding some “White Tack” to the slot solved that problem.
The Ranger has been fitted with a loop of beige bootlace about 14 cm long. So too has my mini‑Leatherman Squirt P4.
Both tools ride in a mobile phone belt case with cut‑out bottom corners.
The loop of cord is passed down through a corner and then the tool passes through the loop to form a lark’s head knot. Even if the top of the pouch pops open, the two tools cannot be lost.
The loop is also large enough to pass around my wrist or hook my thumb through for added security when using the tool. The safety pin may be used as a pin or clip to secure the tool to clothing or D‑rings. I also plan to fit a pocket clip to the Ranger.
The pouch mentioned above is on my trouser belt. If I am wearing trousers, I have my Swiss Army Knife and mini‑Leatherman with me. I will also have my keys, so will have my Classic SD available too. The belt pouch also holds the aforementioned pocket pry bar and a diamond‑impregnated metal sharpening card.
The few jobs the Ranger is not suited for, the mini‑Leatherman or pry bar can usually handle.
If this collection of tools cannot handle a job, they may often be capable of making something that can.
The tools form a component of the EDC kit I have distributed across my keyring, trouser pockets and compact pouches on my trouser belt.

Summary

The Swiss Army Knife is the tool I am most likely to have with me when I need a tool. It is worth spending a bit of money to get one you are happy with.
That said, the web currently lists the Victorinox Ranger as $75, with the lesser bladed models at correspondingly lower prices.
Given the very high quality of Victorinox knives, that is a pretty reasonable price compared to the prices of some other folding and fixed blade knives.

Survival Library: Chapter 9, Jack-Knife Cookery

Roll back to the start of this century, and you would have found me practising cookery in a mountain hut in the middle of Iceland.
I had found myself part of an impromptu group hiking over the mountains.
While most of my companions tucked into their freeze‑dried rations, I busied myself cooking my dinner in my Kephart‑inspired cook kit.
I do not remember exactly what I was cooking, but it was based around some rice. Among the foodstuffs I carried was included rice, flour and “Alpen” (a brand of muesli).
Cooking a meal from base ingredients was considered to be somewhat eccentric by my fellow hikers. It was, however, admitted that my meal looked far more appetising than theirs! I was probably carrying less weight of food too.
The following day, a beautiful German girl scrutinized by every move with great interest as I improvised an Alpen bannock, cooked in my home‑made folding handled frying pan.
Cover of Jack-Knife Cookery
Carrying flour and knowing how to make use of it on the trail I can attribute directly to my acquisition of “Jack‑Knife Cookery” by James Austin Wilder.
Not to be confused with an inferior book of similar title by the “Woodsman’s Thong” (!)
The real Jack‑Knife Cookery book was first published in 1929, but has undergone several reprints. My copy dates from the twelfth printing from 1965.
Written for boy scouts, this book begins by proposing a scenario where you have only flour, raw meat and a jack-knife. How would you go about feeding yourself?
The reader is then introduced on how to cook “twister” and “kabobs”, both of which may be cooked on green sticks over a “plug‑hat hole” fire.
Twister bread cooked on a stick
From here, Wilder introduces the reader to cooking dampers and other foods, cooking on or in coals, “Imu” cooking, how to cook vegetables without a pot, mixing without a bowl, how to cook in a billy, making stews and many other useful subjects.
All of this is illustrated with Wilder’s own drawings and anecdotes/“yarns”, so is clear and highly readable.
Having fed the inner (young) man and grabbed the attention of the reader, Wilder moves on to discuss camping and related topics.
This is 1920s’ style, of course, so of interest to anyone who understands that they may have to survive outdoors without Goretex, GPS and freeze‑dried rations.
The third part of the book logically drifts into survival and emergency advice, peppering it with additional recipes and cooking techniques, including fun stuff such as boiling water in a glass bottle.
One oddity is Wilder’s alternative to Morse Code.
The section on friction methods for starting fires is entertaining, if not as technical as that in “Northern Bushcraft”. This section includes a story about using a fire‑plow/fire‑plough, a technique many survival manuals do not bother to include. There is also a “sawing” friction method using sections of bamboo which I do not recall often seeing in other works.
This book has been a great influence on many young outdoorsmen, myself included.
To this day, I may sometimes be found in the kitchen mixing flour and sultanas together when I feel peckish.
Jack‑Knife Cookery is a great book. I treasure my copy, which sits in pride of place on my shelves next to “Camping and Woodcraft”. I thoroughly recommend adding a copy to your survival library.
Now the bad news. I have been unable to locate an on‑line or Kindle copy of this book. The only search engine hits I get are dodgy sites with bad English that want your credit card details first, so steer well clear of those.
Printed copies may be found, although on‑line prices tend to be high. I have seen copies offered for as little as $30, so shop around before you part with hard‑earned cash.
If ever a book should be preserved on Internet Archive, it should be this one! If anyone reading can make that happen, make it so.

Fishing with a Soda Bottle, Done Right!

As mentioned in my previous review, the section on fish traps was one of the more deficient sections of “The Official John Wayne Handy Book of Bushcraft”. There is a mention that one of the means you can make a fish trap from is from a water bottle. It is also stated that traps will only catch very small fish.
A friend of mine recently mentioned using soda bottles as fish traps.
Typical plastic soda bottle fish trap
The way this is usually shown, a cut is made just below the conical section of the bottle. This part is inverted and inserted into the rest of the bottle.
Obviously, only fish small enough to swim through the nozzle can enter the trap.
Not much of a meal!
I began to think about ways to improve on this. The obvious one was to cut off the nozzle and provide the trap with a bigger entrance.
Keep the neck to make a useful clip.
Before I could think too long on this, I was reminded of one of my favourite youtube channels.
This features a very ingenious lady in Cambodia.
Check out some of her other videos, which feature PVC fishing bows, recipes and many other varieties of traps.
◦ Note that the screw‑threaded part is removed and the area around the new opening cut into “petals”. In this video the petals are clearly shown being cut into points.
◦ Holes have been made in the base of the trap so water flows through. This lets the smell of the bait out to attract fish. This also allows them to drain as they are removed from the water.
◦ Each trap has a closed smaller bottle attached to it to act as a float and suspend the trap clear of the bottom.
If aiming for bottom dwelling fish, you may need to weight the trap.
◦ The funnel part of the bottle is secured to the larger part. This is a good precaution if aiming for larger fish.
When I first started watching this I thought she was cutting “V” shaped tabs in the outer part to hold the funnel in. That should work.
What she is actually doing is making holes and securing the two parts with cord [or you could use grass or plant stems].
Reaming matching holes and using wooden pegs carved from a stick would make the trap easier to take apart to remove the fish.
This site shows the innovation of a flap cut in the funnel for easy removal of fish.
Such a trap can easily be made with just a penknife with a reamer.
Four good‑sized fish from three traps is pretty good going!
For many other uses for plastic bottles, take a look at Plastic Bottle Cutter's channel!

Survival Library: Chapter 8, John Wayne

Trivia: I share my birthday with John Wayne. Some years, a TV channel will schedule a day of his films. Good, unpretentious entertainment! That is me sorted for the day!
I once watched something where a character declares “I try not to have high expectations. I am, therefore, seldom disappointed. Occasionally, however, I am pleasantly surprised!”
John Wayne Bushcraft cover
That is not a bad philosophy, and I was reminded of this when I began to read “The Official John Wayne Handy Book of Bushcraft”.
This could be really bad, have hidden pearls, or just be a bit of a giggle.
Firstly, I will answer a question I usually save until the end of these reviews. This book should NOT be used as a primary survival guide. Some fields are omitted, others lack adequate detail.
Some of the content was useful. There is a section on dealing with a riptide, which is not a topic I have seen in many manuals,
Each section is only a few pages long, so I expect much of this content was originally an article in “The Official John Wayne Collector's Edition” magazine.
Many of the sections only deal with a single topic or subject, such as a single type of knot or a particular type of campfire. That works well for certain topics and is a presentation style I may experiment with.
In other places, the treatment of the topic is rather brief, and in a few places additional illustrations would have been useful. The latter is odd, since in general the book is quite well illustrated, both with drawings supporting the text and photos from Wayne’s films.

Tools

The book starts with a section on how to make a variety of tools using primitive means. No mention is made of the risk of silicosis from stone knapping. Improvise a nose and mouth covering when making stone tools. Eye protection, if you have it, is also prudent unless you are a big Rooster Cogburn fan.
Several places in the text you are told to hit the back of an axe or knife blade with a stick or stone. Do not use a stone! The technique is called “batoning” for a good reason.
If you made yourself a stone knife as suggested at the start of the book, hitting it with another stone will waste hours of your careful work!
The section on making a whistle was disappointing. Acorn cups may be quite hard to find in certain seasons and regions.
The section on making a bow shows the first finger hooked over the top of the arrow, which must result in considerable friction.
Correctly, the book advises that hunting with a sling requires a vast quantity of practice. Incorrectly, it says the weapon is also called a “slingshot”. [Wikipedia also gets this wrong!] Sling and slingshot are quite different weapons using quite different principles.

Knots

The chapter on knots deals with one knot per section.
In some of these sections more information on the application of such knots might have been useful.
For example, the Alpine Butterfly knot is covered, but no mention of the quick and handy way this may be tied.
The section on the half hitch actually shows two half hitches in the illustration.

Food and Water

The chapter on food and water mentions water tapping from trees, which some survival manuals neglect.
Distilling water using sun, a bottle and a soda can
The edibility test is described in detail, but no mention is made of prioritising the test for foods that are most abundant in the area.
There are sections on line and rod fishing and fish trapping, but no mention of night/trot lines. The latter section could have used some illustrations of various fish traps.
There is a section on “knife hunting” with a caution on how dangerous it will be and the high likelihood of injury.
Use the knife to cut a stick and make a spear. If in terrain where there are no sticks, you are unlikely to get close enough to use a knife, anyway.

Fire

The chapter on fire I thought was quite good. Some fire‑lighting techniques not often covered, with some useful illustrations.
Some discussion of various types of campfire. Uses for charcoal, and emphasis on properly extinguishing your fire.
Wet rocks in a fire may explode into fragments, not “shrapnel”, which is a different thing.
Using a bottle of water to light a fire
I would still recommend reading the fire discussions in Kephart and Northern Bushcraft, however.
There is a section on using a Mylar space blanket as a reflector for your fire. This is a legitimate application, but perhaps some mention should have been made that a higher priority use for such an item is waterproofing your shelter roof or wrapping yourself.

Shelter

The chapter on shelters was much less satisfactory. It starts with a description on how to cut down a tree because it may be where you want to make a camp! Camp somewhere else, yahoo!
You are told to hang a hammock using a figure eight knot, but no real explanation nor illustration.
Building a raised bed suggests using logs for the short side. Two long logs with shorter sticks between them seems far more practical.
There is a description on how to make a five foot diameter teepee. Not sure what for. I could not lay down in such a space, let alone someone John Wayne’s height!
One of the illustrations incorporates ideas such as using natural windbreaks such as rocks, but seems to show the bed laid perpendicular to the fire.
There is a lot about this chapter I feel could be improved.
One error that really has me scratching my head is that in several sections the authors describe shelters made with “poncho liners” when they clearly mean ponchos.
You would think a retired Green Beret and a SERE course graduate would know the difference.
You would think that the editorial staff of the magazine might have picked this error up.
You would think some of the readers of the magazine might have written in about this obvious error the first time it appeared.
To confuse a liner with a more external layer is itself a really bizarre mistake for native English speakers to make!
“Make a map” could have mentioned that birch bark or similar and charcoal could be used to make a portable map.
The section on tying a tourniquet talks about an overhand knot, but clearly shows either a reef/square knot or a pair of overhands.
Another objectionable section is the recommendation to shoot any snakes on sight!
You should not kill anything unless you have a legitimate reason. This saves ammunition, if nothing else.
As a later section notes, most snakes will not bother you if you leave them alone. If there is a danger of stepping on a snake, carry and use a walking staff.
At the end of the book is an advert for a survival training school where both authors work. The various points raised above do not really form a recommendation.
After finishing this book, I started browsing “The Official John Wayne Handy Book for Men”. This begins with some bushcraft information. I found this description of making a bow and arrows better written. Some of the other articles on the same topics are also superior.
It mucks up the illustration of how to identify the North Star, however.
