A knife for survival, purpose, the need for tools and equipment, dimensions and suitability for use, the concept of three knives.

If you go to any store or open any knife catalog, you can see many so-called survival knives dotted with countless gadgets and tools. 

Survival knife, purpose, the need for tools and equipment, dimensions and suitability, the concept of three knives.

Most survival knives were, at best, designed for pilots who climbed out of the jungle occupied by the enemy. After an emergency landing or bailout from a downed aircraft. And what is permissible and desirable on the territory of the enemy is not always possible on their own.


I will give an example. A hunter or a tourist approached the riverbank, went ashore, the offshore departed, and take it and get rid of it and float away with the stream. The backpack in this situation remained in the boat, you have to get out of the forest with what was with you.

Another option. A random spark from a bonfire or stove set fire to a tent, and a man jumped out, fleeing the fire. Most likely, a knife weighing with a sheath under a kilogram or more in this situation will be lost with the rest of the equipment.

When leaving for a duck hunting camp, few people think about the possibility of getting lost or being cut off by a strong rise in water or bad weather. We conclude that the weight of the knife should be less.

The need for tools and accessories in the knife for survival.

The tools in the knife for survival are a good idea, but their intended use causes difficulties. If necessary, a knife with a screwdriver in the handle turns the screw into a screwdriver, from the handle of which a sharp knife blade sticks out to the side or back. So cut yourself short.

The saw on the butt is almost never bred properly, its length of ten centimeters is clearly insufficient, so it is impossible to cut a tree with it. If the saw, as expected, is bred to one and a half to double the width of the blade, then the knife will tear the sheath, and if used as a weapon it will be very difficult to pull it out.

The saw should have a length of at least half a meter, and preferably longer, but this is no longer a knife, and the sapper broadsword of the mid-nineteenth century will be, and it will relate to long-blade weapons. And enthusiasts who are ready to go hunting with a saber or on a hike will have very, very little.

The compass on the knife is a separate song. They showed me a strange knife. The prototype of the army, as if for special forces. On the sheath the compass is under the lid. Everything is fine, only a huge magnetic blade should affect it, and constant blows to other equipment will not add accuracy to the compass. Yes, and what accuracy from a compass with a diameter of about two centimeters.

The compass in the handle lid, which at the same time was a pencil case underneath, seems to me illogical. To go along the compass, you need to hold it in your hand, and then the pencil case under the NZ will be open and its contents will crumble. And what can be put into the volume of twin-screw sleeves? Is there really no space left in your pockets? And if in a critical situation this knife with a sheath is lost or thrown, still there is a kilogram in it, then with it the compass will be lost.

Dimensions, length and thickness of the blade of a survival knife.

Here, every manufacturer competes with someone who has thicker steel and a survival knife stronger. Savagery against a knife in catalogs is published with photographs. Like, look, we have punched a car door with this knife for survival, or sawed a 20 mm rebar. It would be better to show the hands and facial expression of the one who peeled half a bucket of potatoes with this bar.

The thickness and weight of the blade is argued by the suitability for the construction of shelters or a raft. Noplot in the jungle – this is a few thick branches or a bunch of reeds to put a backpack and, floating nearby in warm water, hold on to your hand. In our taiga and cold, and with our Siberian rivers, not only we have to climb onto our raft, escaping from cold water, but also equip it for a possible round-the-clock rafting.

And this is a booth from the rain for several people, and a playground-center, lined with stones, so that the raft will be at least 3×5 meters. The concept of shelter for a pilot in a warm jungle is a cloak-tent on pegs lined with branches for camouflage. In our conditions, it may be necessary, if not a hut, then a dugout with a coastline, or, conversely, to build a deck on stakes over a swamp.

The width of the blade of many knives, especially those that are being transported to exhibitions, is probably too large. Russian knives are immediately noticeable in a powerful width resembling shovels. One of the definitions of a knife is a stabbing weapon. Well, since the Ministry of Internal Affairs prohibits stabbing with our knives, the manufacturers seemed to decide to make a knife that you can not stab, so bury the enemy. At least as a garden scoop, most knives can be used, transplant flowers there or dig up worms for fishing.

The concept of three knives.

What remains? But nothing new. The world-famous concept of three knives in relation to our climate. Tool knife with a small blade for delicate work, but with screwdriver, tools, awl, file, tweezers. Screwdrivers should be convenient for minor repairs of weapons and adjustment of sights. The purpose of the needle file and the sew is obvious. Tweezers are sometimes needed to pull out a splinter or a bee sting. Can opener for cans.

The second knife is medium in size, awkward type, made of good steel, light and easily washed from dirt, for example, after cleaning the fish. The butt is straight so that you can clear the ice from the skis on a winter hunt. Garda is not needed, except that a small protrusion on the side of the blade, so as not to cut your fingers. From the side of the butt, the guard is not only not useful, but harmful, it makes it difficult to put a thumb on the base of the butt.

Instead of the machete used in the tropics, an ax or a hacksaw for heavy work. I like the saw more, it is easier to work with when it is tired and cold, when only one hand is working or when you just can not make noise. And in a situation of self-defense, the teeth of the saw with one stroke with a pull will deprive the attacker of not only the desire to attack, but also the ability to do anything with his hand at all.

Pricing and Survival Knife Issues.

What can be done with a knife for $ 200, what can not be done with a knife for 20 or less? Interest Ask. The quality of steels both in us and in the West is quite high. Knives of Scandinavian production suit us more than European and American, due to the similarity of climate. Masters are completely equal to the West and surpassed Far Eastern crafts by orders of magnitude better steel.

In an advertisement for knives made of high-tech steels, they write that the steel used for the blades of aircraft turbines is used. What does this give the hunter? Never mind. The turbine operates at 600-800 degrees and without impacts, but impact resistance and the quality of the cutting edge for turbine blades does not matter. The hunter, in turn, does not need gas erosion resistance, does not need uniform expansion when heated to five thousand degrees. Just don’t put the knife into the fire..

Suitability of the knife for self-defense.

The suitability of the knife for self-defense is determined only by the fact that nothing else was at hand, and not by the dimensions of the survival knife or the presence of a guard. Domestic forensic definitions according to the length, thickness of the blade or its shape are not practical for practical use, but must be observed to avoid troubles.

The combat knife Camillus SM-CP75, which is in service with the Western armies, has a blade of 79 mm, Delta dart firm Cold Steel 89 mm. The commando blade Ek also dangled 89 mm, which makes it a household knife according to our laws, and the commandos did not know about this in World War II and cut the German sentinels with might and main. The English OSS Sleeve dagger does not have a guard, and the blade is the same 89 mm. Typical hosbyt in service with one of the most fought special services.

A little bit about the combat knife.

There are combat knives in the West with a 15, or even 25 cm blade, despite the fact that a standard bayonet knife in the USA has a 17 cm blade. And he is scolded for being too long! The secret is simple: the longer the blade, the more power it must be kept working with the tip. That is, the lever is larger, and to hold the knife, you need more effort, which means that the hand will get tired faster.

The thickness of the blade as a criterion of suitability for military use is obscure. You can also stab with a spoke with a diameter of one and a half millimeters. In museums around the world there are enough eastern swords and daggers, the thickness of which fits into our framework of a household knife. Moreover, there is accurate evidence that this is not a ceremonial, but a military weapon. It’s just that steel there is not an easy cast damask steel or welded damask containing vanadium, nickel, and other alloying additives.

According to the Western definition, a combat knife, that is, a combat or army knife, is a knife so strong as to withstand the worst treatment by soldiers, including opening zinc with cartridges and breaking off the lids of wooden shell boxes.

He also has a bunch of requirements that are unnecessary in civilian life. Type of ease of degassing (cleaning) of radioactive or toxic substances, stability in the temperature range from minus 50 to plus 50 degrees, and so on. In modern armies, the use of a knife as a weapon is a rarity, and soldiers are not taught to use a knife. Another knife should be cheap in mass production and simple. Therefore, you should probably refrain from buying an army combat knife for hunting or hiking..

Rather, a knife for self-defense can be a knife that can be worn without attracting attention, light enough and suitable for household purposes, so that there is no desire to leave it at home. And in battle, the psychological mood for victory will be more important than the length of the blade or the presence of a guard. It would be nice if you never needed this knife appointment …
