The Goken Kagayaki #400 is a Japanese sharpening stone made of fused alumina, valued for its efficient cutting and smooth sharpening feel. Its #400 grit is ideal for restoring a dull edge, reshaping a cutting edge, or preparing a blade for finer finishing.

Suitable for knives, Japanese planes, chisels, and carving tools, it offers an excellent balance between performance and ease of use. Delivered with a case that also serves as a stand, it is practical for both the workshop and storage.
