Coupe knife Yoshiyo for bread making

This is a razor blade holder with a plastic handle that fits comfortably in your hand, and the blade itself.

To use, insert the tip of the holder into the hollow of the razor blade and set it so that it bends slightly like a bow, aligning with the fine grooves. (See the first photo.)

The blade is sharp, so please handle with care.
