Yes. The Minonokuni 4000 grit whetstone is designed to sharpen both high-carbon steel and stainless steel kitchen knives effectively. Its abrasive formulation works well with traditional Japanese carbon steels such as Blue Paper Steel and White Paper Steel, as well as modern stainless and high-chromium knife steels.
The 4000 grit surface is ideal for refining and polishing an edge after primary sharpening, helping improve cutting smoothness, edge refinement, and overall sharpness on both Japanese and Western kitchen knives.
