In Praise of Puukko and Mora

On a number of occasions, I have talked about my favourite kukri (I own a few!). This is a ten inch sirupate with a half‑guard and a lengthened grip. This is the tool I will grab when SHTF.
What I have not so far discussed is that my kukri is just one half of a double act. It has a Companion!
With the kukri, I carry a small, fixed blade knife. Both are fitted to the same belt, along with a small pouch containing a fire kit and a sharpening stone. Note wrist loops that may be attached to the snap-links to further prevent the chance of loss.
Kukri, Mora Companion and Fire Kit.
I always have my Swiss Army Knife and mini-Leatherman on me, of course. A small fixed blade is handier, and easier to get clean after a messy task like gutting a fish.
The rationale behind having a pair of fixed blade knives is thus:
Most cutting tasks do not need a large knife. Most such cutting tasks are easier and safer with a small knife. This helps save the edge of the large knife for uses that it is really needed for.
A shorter blade and lighter knife often provides a greater level of control and precision.
A large knife can perform many of the duties of a small knife, but a small knife cannot entirely substitute for a larger blade.
Since the small blade will spend more time out of its sheath than the larger, in theory I am less likely to lose my larger blade. I can manage without the small knife better than I would manage without the larger.

Puukko

When it comes comes to useful small blades, one of the examples that comes to mind is the Finnish puukkot (singular is “puukko”).
Puukkot are about as common as snow in Finland.
Puukkot come in a variety of sizes, but the most commonly encountered are blades of 75 to 100 mm length.
Large production runs and informed buyers means puukkot are produced with good quality blades at reasonable prices. Reasonable in Scandinavia, at least. Crossing the water bumps the price up, but they are still very good knives for the money.
“Fica” knives were apparently once popular with some Russian criminal elements. This is claimed to have inspired the Soviet NR-40 knife. (With its clip point and inverted main edge, the NR-40 has some resemblance to British knuckle-duster knives used in World War One and the Second World War BC41 knife.)
Many puukkot are works of art. Some have handles carved from “curly birch”. Another grip construction utilizes stacks of washers made from reindeer skin or birch bark.
Unmounted puukkot blades are available from some suppliers. If you fancy making your own sheath and grip, I recommend Bo Bergman’s book “Knifemaking”. Not only highly informative, but beautifully photographed and recommended for knife-lovers and other hoplophiles.
I have not yet been to Finland.
I picked up this pair of knives on my last days in Denmark.

The upper example is Finnish, I believe. The grip is curly birch, with a touch of linseed oil to bring out the grain. Note the button hole in the hanger.

For ease of access, puukkot are often carried suspended from the button of a breast pocket on a shirt or jacket.
This knife is also a good size to fit in a cargo trousers’ thigh pocket. Useful if camping in areas where simpletons will freak out if you wear a belt knife openly.
Note also that these knives usually use a deep sheath that covers most of the grip. Such a sheath is very secure, but does limit the provision of a guard.

Mora Knives

I didn’t know it at the time, but the second knife is Swedish, and made by Mora.
Mora (aka Morakniv) are a Swedish knife manufacturer, and their main products are puukko-type knives.
Whether a knife can be a puukko if it is made in Sweden, I will leave for others with more time on their hands to discuss.
Mass production means good quality at very reasonable prices, so Moras are the first choice for many when it comes to choosing a small, fixed blade knife.
Moras are probably at least equal to many knives that are more than five times the price.
The most obvious difference between most Moras and puukkot is that most Moras have handles and sheaths made using plastic rather than wood and leather.
My kukri is complimented by a Mora Companion (model number 860).
I gave another Companion to my girlfriend to compliment her kukri. The Mora proved useful when she was foraging in Sardinia. She also utilised it when gathering seafood when snorkelling. She particularly praised how securely the knife stays in its sheath.
The Companion has a ten centimetre stainless steel blade of a useful and proven configuration.
The plastic sheath is well designed and very secure.The knife positively locks in position and stays in the sheath until you want it. You can quite confidently wear the knife handle down.
A slight bump at the top of the sheath mouth is provided for the thumb to push against if drawing the blade single-handed. You can also push down on the top of the belt-hanger.
The belt hanger is provided with a cut-out for hanging from a button, and the sheath is provided with a drain hole. The hanger itself is a clip, so the sheath may be worn with clip slipped over the top of a pocket or over a jacket edge.
Companions are offered in a wide range of handle and sheath colours. Mine are in a drab green or sand‑colour. Brighter colours are available for those prone to misplacing items.
The Companion, and several other models are available with either stainless steel or carbon steel blades. My preference is for stainless steel, particularly if the knife is going to be stored in a kit and not inspected for some time. Stainless steel is also recommended for fishing knives or any other use that takes you close to salt water.
Carbon steel is better for throwing sparks from ferrite, but is more prone to rusting and discolouration if neglected.
I have various other objects that can throw a spark. My kukri has chakmak and karda. Spark striking is realistically a low priority or me since my EDC includes a butane lighter and there are two in the fire kit on the knife belt. I can even use the striker wheels of the lighters to strike sparks from ferrite rods.
The only modification the Companion really needs is to drill a hole for a wrist loop or lanyard. Since the blade has a rat-tail tang, adding such a channel is a quick and simple task.
A criticism sometimes levelled at puukkot is the transition between blade and grip. The forefinger could slip forward and be cut by the edge at the base of the blade. For most uses this is unlikely, but if in a hurry, forgetful or your hands are wet, is a possibility.
The plastic handled Mora’s include a finger guard, and their plastic sheaths are designed to accommodate this feature.
Some of you reading will be discouraged by the reasonable price of a Mora Companion. It cannot be that good a quality at such a low price!
Given how low the price is, I challenge those readers who think this to take a risk and buy yourself one. Then send me a cash donation as penance for doubting my word, shame on you!
Chances are you will probably invest in a couple more Moras. At these prices, you can stash a spare in your car, your tackle box and so on.

Mora Pro Robust

When I heard about the Mora Robust/Pro Robust, I was eager to get one.
It might be a good option for situations when I can only carry a single fixed blade knife.
Mora Companion, 511 and Pro Robust
I was expecting a heavier bladed version of the Mora Companion. In fact, the Robust is closer to being a heavier bladed version of my Mora 511 (above, top). The grip is the same shape, and both have 9 cm carbon steel blades. The Pro Robust is described as having a 3.2 mm thick blade while the 511 is listed as 2 mm.
The Pro Robust has a beautifully polished blade. I had elected my 511 as the “kitchen Mora” and used it for something without realising it was a carbon steel blade. Leaving it for a short period without cleaning and drying it has discoloured the finish. Won’t make the same mistake with the Pro Robust.
The Robust and 511 have a more pronounced half-guard than the Companion, and consequently the sheath is a little different. Different in details, but not in features and functionality.
Like the Companion, the Robust (and the 511) lock securely into their sheaths. I have been unable to shake it hard enough to persuade the knife to drop out. I will probably pop a joint before I shake it loose.
Rather than a bulge for the thumb to push against, the top of the sheath mouth has a ridged section for the thumb. The design of the button hanging feature is also different. The most obvious difference is the knob/mushroom structure on the front. A similar feature is seen on some bayonet scabbards and is used to secure the sheath in a frog. It is a convenient structure for the fingertip to push on when drawing the knife single-handed.
There is a thicker bladed version of the Companion available, but I have yet to acquire one. This has a 3.2 mm rather than 2.4 mm thick blade.

Scandi Edge

All of the Mora knives I have owned have arrived already sharp with a good edge. Eventually you will need to resharpen, however.
Traditionally, Scandinavian knives were sharpened with what has become known as a “Scandi edge” or “zero grind”.
What this means is that the primary edge and the bevel are the same. To sharpen, you lay the knife’s bevel flat on the sharpening stone and move the blade back (or forward), depending on your preferred sharpening style.
This is very easy to do, but involves removing a lot of steel with each sharpening. The scandi edge is claimed to produce a very strong edge, useful for some applications.
Modern blade steels tend to be harder and better quality than was available to previous generations, so there is reasonable doubt as to whether a scandi edge is the best choice for modern Mora and puukkot, especially those with laminate or stainless steel blades.
There are plenty of forums and videos on the pros and cons of the scandi edge, so decide for yourself what is best for you. Personally, I sharpen my Mora the same way as I sharpen my other blades.
Bergman’s book suggests sharpening blades with an angle of 10 to 30 degrees, depending on intended application.
For a general purpose knife I would suggest an angle of 22.5 degrees. If you lack a protractor or have trouble visualizing this, fold the corner of a piece of paper in half, then fold it in half again. A quarter of 90 degrees is 22.5.
The “kitchen Mora” responds well to the butcher’s steel I use on my other kitchen blades.
If you are looking for a special present for a knife-lover or outdoorsperson, a traditional puukko is worth considering. Something both beautiful and practical.
Morakniv, aka Frosts, make a wide range of other knives, for the kitchen, the outdoors and for the workshop.

Fruit Juice and Knives

A friend of mine has warned me she intends to bring me a knife for some attention. It needs sharpening, but also has some marks. Too much touching the blade and not enough (if any!) oiling.

Gentle Rust Removal

If you paid attention in Science class you will know that you can remove rust with acids such as vinegar. Often this leaves a discolouration, however.
An interesting technique I have used is to remove rust with pineapple juice. Pineapple juice is a very mild acid. If you soak a blade for a few days it gently removes rust patches, leaving much less discolouration. Something like a vase is ideal. Just submerge the blade in juice to the depth required. If you lack a vase then the juice carton itself may be a suitable shape. You may have to brace it so the weight of the knife does not cause it to topple over.
I have only ever used pineapple juice for this, but other fruit juices should work. I suspect grapefruit juice may be too strong, but that is just a guess and I may be wrong.

Fruit and Bread Knives

I was watching a movie recently and a character makes a comment about the wisdom of cutting tomatoes with a bread knife. I guessed this may have been due to most people not having genuinely sharp kitchen knives, but I ran the idea past a chef friend.
My chef friend agreed one should cut tomatoes with a bread knife, and that it should also be used for other acidic fruits such as lemons and limes.
His explanation was that the acid of the fruits prematurely blunted other types of kitchen knife. The serrated edge of a bread knife was less affected by this. He did note that many chefs he had worked with were unaware of this.
So, if you are cutting acidic fruits in your kitchen, reach for a bread knife or serrated blade, preferably one of stainless steel.

Pull-Sharpening for Knives and Tools

My recent project with the machete has spurred me to sharpen a few of the tools I have around.
In my book, “Survival Weapons”, I devote an entire chapter to the topic of sharpening. That chapter remains a useful guide to a topic that can sometimes seem cryptic.
At this point I should explain that one of my “virtues” is that I am lazy. According to admiring colleagues, I can be usually be expected to find the simplest, most stress-free method of getting a job done. Over the last week or so have I noticed that how I sharpen some tools now varies somewhat from the techniques described in the book.
Regular readers will know I own a number of kukris, as well as other large blades. There was this period of ill-health where I spent my holiday budget on swords instead! Probably safe to say I have more large blades than the average prepper. Some of these have concave or convex edges, or in the case of kukris, both. Some of the techniques for sharpening you will see on some websites are not ideal for such tools.
A useful stone for pull-sharpening and an angle-er
I have, over the decades, acquired a large number of sharpening systems. The one I have found myself using the most recently is shown above.
I inherited this stone from a deceased colleague. It is most likely an Arkansas stone. The stone itself is about three inches long and a little under an inch wide. It is firmly mounted (glued?) to a wood tray about four and a half inches long by an inch and a half wide. This provides a very nice handle when using the stone. Beneath the base is the matching wooden lid. The stone has just been cleaned. I used a little washing-up liquid and some water to remove most of the grime. A little bathroom cream cleaner took of the remaining residue.

The Angle-er

The device below I call an “angle-er”. Having this nearby helps you visualize the correct angle while sharpening. This particular example has angles of 22.5, 15 and 30 degrees, which are pretty good choices for general usage. Some may prefer 17 or 20 degree and 35 degree angles. Once you have your tool close to the correct angle it is easy to vary it a couple of degrees if desired.
The beauty of this Arkansas stone is that I can move it instead of the blade. Unlike a larger flat stone this one is narrow enough that it can follow a curved edge, rather than attempting to grind it straight.
The method I use is essentially the same as was described for sharpening a machete, only instead of using a file I use a suitably sized stone.

Sharpening Styles

There are a number of ways that a stone or file can engage a blade. In the movies you often see a stone being dragged down a sword edge. Looks good but I have my doubts as to how useful this would be in the real world. Usually we want the sharpener to pass down the edge with some movement across the edge too.
The sharpening technique most often seen in “how to” guides is what may be called “push-sharpening”. If you were using a large, flat stone, you would move the blade as though you were attempting to shave the surface of the blade.
You will also see “push and pull” sharpening where the blade moves back and forth across the stone. I personally don’t use this method much and would not recommend it for the novice. Keeping the angle constant over the different strokes requires skill and it is easy to over-do things. If you can maintain an angle it is useful for quickly establishing a secondary edge.

Pull Sharpening

These days I tend to use pull-sharpening techniques. As you might expect, the blade moves in the opposite direction to push-sharpening. One of the advantages of pull-sharpening is that it is easier to move the sharpener across the blade edge, rather than moving the blade. This is useful when working on large or awkward blades but can be applied to small blades too. One does not need a workbench or similar for pull-sharpening. I usually sit on the sofa, watching the telly and using the advert breaks constructively.
Pull-sharpening is a good technique to use with small triangular-section sharpening stones. It is also suited to the oval stones sold for sharpening tools such as scythes.
lanskey sharpener
When you use a leather strop you are using an action like pull-sharpening. If you did not you would cut the leather!
If you are sharpening a tool using a high-speed device you should be using a pull-sharpening technique. This is so that if the high-speed wheel or belt snags the blade it will throw it away from you rather than at you!
One reason I like pull-sharpening is it is easier to view the angle of contact that sharpener and blade make. It is also easier to give both sides of the blade similar treatment without trying to use your non-dominant hand or run around the table.

Lubrication

Generally, I do not use lubricants such as oil, water or spit, for sharpening. An article I read, written by a professional sharpener, claimed that his experiments had concluded dry sharpening produced superior results. Much to my surprise, this article can still be found on-line! Generally I only apply water if a stone or sharpening system is particularly crumbly or high friction.

Pull Sharpening Technique

For example, hold your blade with the edge to the left. Place your sharpener at the desired angle, and push your sharpener right to left, moving it away from the blade spine or centre. A “pass” starts at the heel of the blade and moves towards the tip. A pass may take several strokes, depending on blade length and sharpener size. Make three to five passes on a side, then change. For the other side, you have two choices. You can flip your blade over so the edge is to the right and stroke the edge left to right; or you can turn the blade upside down and stroke the other edge right to left. Use whichever technique you prefer and better suits the tool being sharpened. Keep changing every three to five passes, reducing the number of passes as your tool approaches the desired sharpness.
Pull sharpening is a good technique if you are not that confident about your sharpening skills. It is easy to check and maintain the desired angle. It is also not a particularly aggressive technique, so you are unlikely to damage your edge. In fact, I recommend you try a very light touch as you make you strokes and passes. Let your stone trace the curves of the blade rather than trying to remove them. You will find that as the edge geometry takes shape, you will be able to feel when the stone or file is at the correct angle. Light pressure also lets your feel where sections of the edge have irregularities and need more work.
So far, the only problem I have had with pull-sharpening was with a particular multi-tool where the blade was unlocked and rather loose in the open position. Pull-sharpening tended to pull the blade closed. This would only have been a danger if I had wrapped my fingers around the grip while sharpening, rather than holding the back of the blade.
Pull-sharpening is a useful technique to add to your repertoire. The knives in my kitchen are kept sharp mainly by a butcher’s steel and a set of crock-sticks I have in a cupboard there. I maintain my assertion that crock-sticks (ceramic rods) are a very good way to teach yourself the fundamentals of sharpening. Crock-sticks are a form of push-sharpening, but pull-sharpening has improved my technique in using these too. Rather than just slicing down, I now use a lighter touch and let the stick surface trace alone the curve of the edge, keeping contact to the very tip and engaging the edge at a better angle throughout its length.
I think one of the most important things I have learnt in decades of sharpening is that it is another of those skills where less is more. You will get much better results maintaining a light contact with the sharpener rather than pressing down.

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.
