Japanese Natural Stone

Komon's Japanese natural stones are each selected carefully and evaluated for their distinctive qualities and consistency. On each product page, you can review detailed visuals showing the stone in both dry and wet conditions, as well as photographs and videos of blade tests that demonstrate slurry formation and real sharpening behavior.

EXCLUSIVELY FOR FINISHING AND POLISHING STONES

Natural stones used as finishing stones are broadly categorized by grit—from coarse stones to medium stones and finishing stones—each serving a different stage in the sharpening process. Among these, Komon focuses specifically on stones used for final finishing applications.

The reason is simple and fundamental. When natural stones are used in the final polishing stage, they reveal characteristics that cannot be replicated by synthetic abrasives.
The blade develops a unique edge quality and surface finish that can only be achieved through natural stone polishing, resulting in refined cutting performance and a visually deep, organic appearance.
