For the production of unusual and unique knives, which materials alone do not use today: chains from motorcycles, steel cables, bearings, etc. Here is the old lever-type gas wrench, which has long been unnecessarily in the far corner, can also be used as the basis for making a knife with the original name is "Viper Fang."
As a basis, we will use only the stationary L-shaped part of the pipe gas wrench. First of all, the workpiece must be heated red-hot, and then leveled on the anvil, “beating” it with a sledgehammer to the desired size and giving the shape of a snake fang. Then we process the surface of the knife on a grinding machine.
Hardening and sharpening the blade
After grinding, we reheat the workpiece again and temper it in oil, so that the cutting part of the knife will hold sharpening well. In the process of steel hardening, it is necessary to heat the blade gradually in order to exclude the possibility of the formation of large grains in the metal structure. If you heat up the workpiece quickly, then the finished product will turn out to be brittle.
After the hardening procedure, you can go directly to sharpening the blade. Note that the rails are on the outside. First we perform rough grinding, and then finish. It is important to remember that the formation of the slopes of the blade and the sharpening of the knife itself must be performed with the cutting edge up.
The result is a knife of an unusual shape, which is completely different from the classic kitchen and hunting knives. Actually, one can also understand the "unconventional orientation" of the blade from its name. The detailed process of making the knife "Viper Fang", see the video on the site. Write what you think about this form of blade.
