Knife for a man has long been the main weapon. After all, people have neither fangs nor claws to defend themselves - the blade has become their replacement. Initially, it was stone, but humanity moved forward, and knives were also improved. Steel appeared, and then they learned how to make its various grades, thanks to which it became possible to give products different properties. A knife for a person is now indispensable. Here we will study in detail the question of how to make a knife with your own hands so that it meets all the requirements of the owner.

A good blade is especially necessary for people involved in extreme sports far from civilization, as well as foresters, rangers, fishermen - that is, all those whose activities or hobbies are connected with wildlife. If something unforeseen happens under such conditions, then a durable and comfortable knife, with its skillful use, can save a life. The most important thing is that it is convenient for the blade to perform various work. For example, butchering fish, cutting wood, and defending yourself when attacked by a beast. Now on sale there are many different variations of knives, but in most cases their quality is very poor. Nothing else remainshow to make a knife with your own hands at home. Only then will it be possible to know that the blade will definitely not let you down and will be able to fulfill all the obligations assigned to it.

What is the easiest knife to make?

Depending on the material and manufacturing technology, blade to blade is different. The simplest way is to make a knife by cold forging. Various garden tools can become the material: shovels, choppers, saws - there are a lot of options. This material is quite malleable, and a knife made of such steel does not dull for a long time.

Production process

Thinking about how to make a knife with your own hands at home, you need to first get the tools. We will need:

• Hacksaw.
• Files: one large and the rest smaller.
• Vises are optional, but they make the process more convenient and faster.
• Sandpaper.
• Drill.
• Hammer.
• An anvil or piece of rails.

We take a broken or unnecessary garden tool and draw a sketch of the future knife on it. After we start creating this form. To do this, you can use a drill: drill a lot of holes in the shape of the workpiece, then break off the excess and level the surface. If the shape of the knife is simple, then immediately proceed to sawing with a hacksaw. To do this, it is easier and more convenient to clamp the material in a vise - this way it will hold tightly without jumping out. When the shape is cut out, it needs to be finished with a file. Where a lot of metal needs to be removed, a large file is used, after which moresmall. So, the knife blank is ready, moving on to understanding how to make a knife with your own hands.

Recycling

In order for the cutting edge of the blade to keep sharpening well, it must be riveted. This is called the cold forging method, because, without heating the metal, it is simply riveted. Garden tools have carbon steel, but it can be riveted. On a rail or anvil, we rivet the workpiece in the place where its cutting edge will be. During this process, the shape of the blade can be slightly bent, because the metal is deformed, on the one hand - shrinking, and on the other - expanding. However, this deformation is insignificant and almost does not change the appearance of the knife.

Knife finishing

After the cutting edge is riveted, the knife is polished - this is required in order to remove bumps from impacts. Some people like to see marks like that on their knife and leave them. But here everyone has their own preferences regarding how to make a knife with their own hands and what its appearance will be. However, from a practical point of view, it is better to make the blade smooth so that all dirt can be easily wiped off its surface. After all, moisture can linger between the dents, which will lead to corrosion, and this is undesirable. Also, when cutting hardwood, it's better for the blade to pass through the grain well, rather than clinging to them.

Hot forging method

To make a serious knife, the blade of which couldTo cut nails, a more complex processing process is needed. First, choose the right material. You need steel with a high carbon content. From what you can find at home - these are files, drills, springs from cars, as well as spring steel. From this material you can make a hunting knife with your own hands, which will be much better than those offered in stores.

Hot forging process

To do this, you need a furnace in which you can heat the metal strongly. It can be built of red brick, plastered with clay and heated with coal, providing a strong air flow so that the temperature is higher. After the iron is hot, you can start forging. And then - to form a blank until the blade takes the desired shape.

Knife tempering process

Blacksmiths learn for a long time to determine by the color of hot metal when it should be tempered by immersing it in water or oil. However, for the layman there is one universal way. When the steel is red-hot, you need to bring a magnet to it: if it is attracted to the blade, then you should continue to heat it, and if not already, then you need to immerse it in water or oil - for hardening. Knowing the basics of how to make a knife with your own hands, you can improvise to create various models of edged weapons.

An excellent knife can be made from a drill. They heat it up and, holding it in a vise, untwist it. After you get an even rectangle, the blade is given the desired look. From this material you can make a Finnish knifeexcellent quality by hand. After the workpiece has taken the form of a blade, it is hardened, as described above.

How to make throwing knives with your own hands?

To make such a weapon, it is not necessary to have good steel. After all, if you take a material with a high percentage of carbon, then with an unsuccessful throw, the knife may break. Therefore, softer steel, but with a thickness of 5 mm or more, is quite suitable. This is necessary so that, firstly, the blade has sufficient weight, and secondly, it does not bend. It is easy to make it by cold forging, after which you just need to grind it to make the surface even.

However, you need to remember that the center of gravity of the throwing knife should be strictly in the center or shifted more towards the blade. The manufacturing process of such a knife is quite easy, on the one hand, however, on the other hand, it is quite painstaking due to the fact that it is necessary to center the knife. The handle can be made lighter by drilling through it.

Flip-knives

They are quite convenient for the city, because they take up little space and are very convenient, but with prolonged use, their mechanism can become clogged and work poorly. It is not very convenient to constantly use such a knife during work, but if there is no alternative, then for a short period of operation it can be a great helper. To make a switchblade knife with your own hands, you need to choose a reliable mechanism in which the blade will not loosen. It is better to give preference to the model, inwhich the blade pops up from the side. Indeed, as practice shows, if the blade is well tightened and equipped with bearings, it will not loosen for a long time. But in knives with a frontal ejection of the blade, the backlash of the blade is inevitable and only increases in operation. This is more of a stylish toy than a tool.

This article looked at all the ways to make a knife with your own hands. Of course, this is a rather time-consuming process that requires considerable effort, and in some cases, technical devices. However, the result is worth it, and the thing will last for many years.
