How to make a knife with your own hands at home?

Knife for man has long been the main weapon. After all, people do not have fangs or claws to defend themselves - their replacement was the blade. Initially it was stone, but humanity went ahead, and the knives also improved. Steel appeared, and then learned to make various of its brands, so it became possible to give products different properties. The knife for man is now irreplaceable. Here we will study in detail the question of how to make a knife with our own hands, so that it meets all the requirements of the owner.

A good blade is especially necessary for people engaged in extreme sports far from civilization, as well as foresters, huntsmen, fishermen - that is all those whose activities or hobbies are related to wildlife. If something unforeseen happens in 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 do various work. For example, to cut a fish, cut a tree, and also to defend when attacking the beast. Now there are many different variations of knives on sale, but in most cases their quality is very poor. It remains nothing but to make a knife with our own hands at home. Only then it will be possible to know that the blade will not fail and it will be able to fulfill all the obligations imposed on it.

What makes the knife easier?

Depending on the material and technology of the blade, the blade is different. The simplest way is to make a knife by cold forging. The material can become a different garden tool: shovels, hoes, saws - a variety of heaps. This material is pretty pliable, and a knife made of such steel is not dull enough for a long time.

Manufacturing process

Reflecting on the question of how to make a knife with your own hands at home, you first need to acquire tools. We will need:

• Hacksaw for metal.
• Files: one large, and the rest smaller.
• Vise is optional, but with them the process will be more convenient and faster.
• Sandpaper.
• Drill.
• A hammer.
• An anvil or a piece of rails.

We take a broken or unnecessary garden tool and draw on it a sketch of the future knife. After we start creating this form. To do this, you can use a drill: drill a lot of holes in the form 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. For this it is easier and more convenient to clamp the material in a vice - so it will hold tight without jumping out. When the shape is cut, it needs to be finished with a file. There, where you need to remove a lot of metal, use a large file, and then process the smaller. So, knife preparation is ready, we move on to understanding how to make a knife with our own hands.

Secondary treatment

To ensure that the cutting edge of the blade is well gripped, it must be riveted. This is called the method of cold forging, because, without scorching metal, it is simply riveted. The garden tool has carbon steel, but it can be riveted. On the rail or anvil rivet the workpiece in the place where its cutting edge will be. In this process, the shape of the blade may slightly bend, because the metal is deformed, on the one hand - shrinking, and on the other - expanding. However, such deformation is insignificant and almost does not change the appearance of the knife.

Final treatment of the knife

After the cutting edge is riveted, the knife is ground - this is required in order to remove the bumps from the impacts. Some people like when they see such traces on their knife, and they leave them. But here everyone has his own preferences about how to make a knife with his own hands and what will be his appearance. However, from a practical point of view, it is better to make the blade smooth, so that all dirt is easily wiped off its surface. After all, between the dents, moisture can be retained, which will lead to corrosion, and this is undesirable. Also, when cutting a hard wood, it is better that the blade passes through the fibers well, and does not cling to them.

Hot forging method

To make a serious knife, the blade of which could be cut nails, you need a more complex process of processing. First, we choose the right material. You need steel with a high carbon content. From what you can find at home - it's 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

For this, we need an oven in which it will be possible to heat the metal strongly. It can be built of red brick, coated with clay and heated with coal, ensuring a strong flow of air so that the temperature was higher. After the iron has heated, you can start to forge. And after - to form the workpiece, until the blade takes the necessary shape.

The process of knife hardening

Blacksmiths learn for a long time to determine the color of hot metal, when it is hardened, immersed in water or oil. However, for the philistine there is one universal way. When the steel is heated, it is necessary to bring a magnet to it: if it is attracted to the blade, it should be further heated, and if not already, then it is necessary to immerse in water or oil - for hardening. Knowing the basics of how to make a knife with your own hands, you can improvise creating different models of cold weapons.

A great knife can be made from a drill. He is heated and, clutching in the vice, is untwisted. After the rectangle has turned out, the blade is given the desired appearance. From such material, you can make a Finnish knife with your own hands of excellent quality. After the procurement has taken the form of a blade, it is hardened, as described above.

How to throw a knife with your own hands?

To make such weapons, 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 can break. Therefore, a softer steel, but with a thickness of 5 mm, is suitable. This is necessary in order, first, that the blade has enough weight, and secondly, it does not bend. To make it easily by the method of cold forging, after which it should be simply ground to make the surface smooth.

However, it must be remembered that the center of gravity of the knife for throwing should be strictly in the center or displaced more towards the blade. The process of making such a knife is easy enough, on the one hand, however, on the other hand, it is rather laborious because it is necessary to center the knife. The handle can be made easier by drilling it.

Folding knives

They are quite convenient for the city, because they occupy little space and are very convenient, however, with prolonged use, their mechanism can become clogged and work poorly. Constantly using such a knife during work is not very convenient, but if there is no alternative, then for a short period of operation it can become an excellent assistant. To make a folding 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 in which the blade pops up on the side. After all, as practice shows, if the blade is tightened well 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 is only increasing in operation. It is more a stylish toy than a tool.

In this article, all ways of how to make a knife with your own hands were considered. Of course, this is a rather laborious process, requiring considerable effort, and in some cases also technical devices. However, the result is worth it, and the thing will last for many years.
