What steel is best for knives?

In fact, the material requirements of cutting tools are not very complicated. They have enough hardness and toughness to grind sharp edges and toughness, and will not break when chopping. In fact, such materials are not difficult to find, and spring steel is also very easy to use. As long as the heat treatment is proper, you can get a good knife.

Spring steel is used in many places, such as clockwork and spring .............................................................................................................................................................. <

As for the production method, I believe everyone knows it very well. Let me say one more thing. Of course, forging is the best way. When forging, it is best to fold it several times, so that the direction of the metal streamline is basically the same as that of the blade, so that the blade can get the maximum strength and the composition is relatively uniform.

Heat treatment, I think this is the most critical. I think the heat treatment should be carried out after the grinding wheel is sharpened, and the blades after heat treatment should be finished. Remember to get wet to avoid annealing.

The quenching temperature of spring steel is generally around 850 degrees, which is difficult to control. If you look at it with your eyes, the red, white and shiny ones will basically be fine. Oil is used for quenching.

After the above process, you can basically get a knife with both sharpness and toughness. Whether it's beautiful or not depends on your craftsmanship.
