Can you suggest how to use it, when to use the 4000 and when the 1000?
Thanx and bye, Gianni
The 1000 grit stone is for establishing the edge, it is used to create, hone and refine the overall bevel that forms the edge of the knife. The 4000 is specifically hone and polish the edge of the bevel, this is what creates the ultra fine cut, and the smooth feel of the cut. Many Japanese blades come polished to a 6000 to 10,000 grit, which is a mirror polish, makes the blade feel scary sharp to most people.
