How to grind the new knife?

Just grind it on the grindstone with a knife.

Introduction:

When the knife is burning, the iron or steel on the surface will be oxidized or contain high carbon content, which will become brittle. As the saying goes, sharpening the knife is not a mistake for the woodcutter, that is, grinding these off at the knife edge to expose the steel part, which will be sharper. There are two ways of manual and machine cutting, and manual cutting is sharper.

Cutting angle:

1. 17 degrees: it is the angle of a general razor or kitchen knife, and the blade is sharp but not lasting.

2.20 degrees: it can provide a fairly sharp edge, and you can use a knife or a knife that is not very sharp.

3.25 degrees: the cutting angle of the sharp continuous blade. Generally, knives are used in the field at this angle.
