Despite the diversity in the modern market, homemade knives are sometimes valued higher. It is often quite unpretentious looking handmade knife to hold much more convenient than the product of the famous arms company.
Before proceeding with the manufacture of the knife, the first thing to do is decide on its main purpose: whether it will be used as a weapon or will it become an ordinary kitchen knife, or maybe we want to make a universal thing that is useful in any situation. For example, avid hunters prefer to use homemade hunting knives because of their functionality. The same knife can help in different situations: with it you can finish off small game, chop branches for a fire, cut bread, and even protect yourself if necessary. Such knives must have certain dimensions and design. As a rule, their blades are quite wide. They have a shape that makes it easy to skin the game.
So, we found out that homemade knives can have different purposes. Next, you need to search for suitable material for the manufacture of the blade. You can use strips of sheet metal, saw blades, car
springs, knives for electric saws and much more. It should be borne in mind that some types of steel are subject to the formation of microcracks during stamping, therefore blanks should be taken with an allowance that will be cut during mechanical processing.
Homemade knives from machine saws and other
cutting tools can be made in two ways. First: you can release the workpiece, then give it the desired shape and harden again. In the second embodiment, a red-hot billet is processed. It is advisable to use this method if there is no possibility for high-quality heat treatment of the workpiece. Such homemade knives will require additional efforts in the manufacture, since it will be necessary to give the necessary shape to the blades on an abrasive stone. In addition, you must constantly monitor the temperature of the workpiece: it must not overheat, otherwise it may be released. Therefore, it is especially important to prevent overheating of the cutting part of the blade. Moreover, it is very difficult to drill holes in red-hot workpieces. Sometimes you even have to sacrifice a few victorious drills.
The next step is grinding and polishing the knife. These processes directly depend on the technical capabilities of the wizard. For example, it is possible to carry out processing on a grinding machine, or it is possible to manually handle different types of emery cloth.
Design features of a particular knife model provide for separate grinding and polishing of the blade or its processing together with the handle. The last operation is the sharpening of the finished knife and the final fine-tuning of its cutting edge.
But homemade knives are not only a sharp blade of the necessary shape, but also a convenient, correctly made handle. Depending on the shape and size of the blade, as well as on the purpose of the knife, a suitable handle is selected.
