What is a file

What does the editor tell you about a file? The file is forged from carbon tool steel T12 and T13, then annealed and ground for correction. The file teeth are cut out by a file cutting machine and then quenched, with a hardness of generally 62~67HR

A file is not suitable for making a kitchen knife. The material used for making a knife can be spring steel. Generally, knives used in daily life are made of steel clips, while a file is made of all steel with toughness but no flexibility. In theory, it can be made into a knife, but it is not very suitable for making a kitchen knife because the edge is relatively brittle after grinding, and it is easy to cut or break when chopping hard ingredients. Suitable only for cutting foods such as vegetables and noodles.

The file used in daily use has a brittle toughness, and after heat treatment (annealing), its toughness can be improved, which can facilitate processing and reduce the probability of blade breakage.

In a sense, a file is a good choice for making cutting tools! Through heat treatment, suitable hardness and inherent "natural" texture can be obtained, resulting in the production of cutting tools with important characteristics inherent in the material itself. In addition, the level of craftsmanship varies, and the use of main and auxiliary materials also has advantages and disadvantages. Therefore, the produced works have their own characteristics.
