How to make an obsidian knife

Make your own knives with or without forging

Determine the scope of doing it yourself

Do-it-yourself has always enjoyed a completely different status than simply buying things. There are three ways to make a knife.

1. Do the whole thing yourself, all the individual parts and, if necessary, mechanics including the forging

2. The use of a forged knife blade and the “around” building of a handle or blade bed with a folding mechanism.

3. Build yourself with a prefabricated kit according to the instructions, in which all required components are prefabricated.

Of course, the choice depends heavily on your own ambitions, manual experience and skill and the equipment and tools.

Recommended procedure for first attempts

In an initial attempt at building a folding knife or a pocket knife, a kit is recommended. When building it yourself, the hobbyist gets to know the internal structure and the locking and movement mechanism in detail. If you want to make a knife with a fixed blade yourself, the first attempt with a finished blade is the ideal start. In order to forge the knife blade itself, steel has to be sawed, heated and ground. Knowledge of steel types and processing methods is required.

How to build a knife with a standing finished blade yourself

Many manufacturers and suppliers of pre-forged blades are located in the Scandinavian region in particular. The blanks are made of blade steel and are roughly pre-ground. The cutting edge and the blade face are connected to a shaft that is inserted into the handle.

The knife shaft has two to three holes through which screws or rivets are later driven for attachment. When deciding which material the handle shells should be made of, you have several options:

  • Wood
  • plastic
  • Synthetic resin

The rule of thumb among professional knife makers is to only ever use one type of material. However, synthetic resin can also be used as an adhesive and storage connection for wooden handles.

Carbon steel is the best type of steel. Stainless steel is unsuitable for your own production. The steel plate should be three to six millimeters thick.

With a hacksaw, the recorded blade outline is sawn out as tightly as possible, so that the least possible material removal must take place during subsequent grinding.

After the outlines have been ground out with a side grinder or a flex, the two to three mounting holes are drilled in the shaft.

In the annealing furnace, the blade has to be annealed in orange several times, depending on the type of steel. The knife must then be left on in the oven by reheating it.

The Boker Manufactory in Solingen regularly offers courses on building a knife yourself. Above all, you will learn a lot here about the manufacture of a blade. Information can be found at
