Making a folding knife from a bolt Greetings to all lovers of tinkering, I propose for consideration the instructions for making a small folding knife, which the author decided to make from a bolt. The knife handle is made of wood, the blade is simply clamped by the wood in the open state, there is no additional locking mechanism. Of course, not every bolt or stud is suitable for a good knife, you need to choose high-quality bolts that are hardened, they are made of carbon steel. If you are interested in homemade , I suggest you study it in more detail!
Materials and tools used by the author:
List of materials:
– good steel bolt or hairpin;
– nail;
– piece of metal tube;
– piece of wooden board for the handle.
List of tools :
– oil for wood;
– joiner's glue;
– mini-lathe;
– drill;
– polishing machine;
– forge and forging tool ;
– belt sander;
– grinder (angle grinder).
The process of making homemade products:
Step one. Forging
The first step is to turn the bolt into a plate, and already a blade can be cut out of the plate. We heat the bolt to a bright red glow and work with a hammer until the desired result is achieved. By the way, you can determine its type by the color of the glow of the steel. Carbon steel glows bright yellow, while regular steel has more red tones.

Cutting out the blade
Then the author transferred the template to the metal and cut out the profile with the help of a band saw. You can also cope with the task with a hacksaw, until the steel is hardened, it is soft.
Further, the author grinded the profile on a belt sander, using the same machine, the bevels were removed. The final touches can be made with a file and sandpaper.

For the handle, choose a beautiful and at the same time hard wood. The author had a board, we cut it into two strips and glue them together to make a block. The glue must be chosen as reliable as possible so that the handle does not fall apart from getting wet, and so on.

We go through sandpaper and we get an excellent smooth handle. The author made a cut along the cut under the knife blade.
Step four. Reinforcing rim and finishing the handle
Cut out a reinforcing ring for the front of the handle from a piece of stainless pipe. It would be nice to choose a steel that is at least a little springy, so that it squeezes the wood and presses it against the blade. We also make a cut in the ring and drill a hole for the pin.

The oil will prevent the wood from absorbing water and dirt if the knife gets in the water.
Step five. Final revision of the blade
If the blade was made of good steel, it can be tempered. Heat the steel to a yellowish glow and immerse it in oil. The author checked the steel with a file, it is not taken, which means that the hardening was excellent. Of course, after that, it is recommended to release the steel so that it is not brittle.

We drill a hole in the shank, if we haven't done it before, now the steel is hard and a regular drill will not take it. You can use drills for ceramics, glass, and so on.
Step six. Assembling the knife
Assembling the knife, the blade is attached to the pin, rivet both ends. The wood should squeeze the blade so that it comes out tightly, then the blade will be well fixed when working with the knife.

Of course, such a sharp knife is not very safe to handle; it is better to slightly dull the blade for household tasks.
