1. Surface grinding method. This is a grinding method that takes into account both sharpness and hardness. It is ground flat from the back to the blade, so it has a very strong back and ridge. Compared with the above two methods, this grinding method is more difficult to grind because many steels need to be ground during the grinding process. The blade is very thin and sharp. This is a very good grinding method. Because it is a V-shaped starting from the longitudinal section of the knife, it is also called a V-shaped grinding method.

2. Cavalry grinding. Similar to the surface grinding method, it is a design without grooves on both sides of the tool surface. The method of sharpening is the grinding method from the back of the knife to the back of the knife. It also has excellent cutting and cutting ability. The early cavalry knife was this form of sharpening, so it was called the cavalry sharpening method.

3. Arc grinding method. This grinding method is different from the above four grinding methods. While other grinding methods form bevels or grooves on both sides of the blade, the arc grinding method forms a double convex arc above the blade. This grinding method is as strong as flat grinding and as sharp as concave grinding. This is a very difficult grinding method.
