A shirasaya is a plain wooden scabbard made to house a blade when it is not in use. Its purpose is to protect the steel through close contact: the interior carved to the exact dimensions of the blade it holds.

You trace a real katana, then carve the wood form. You work the interior until the blade sits cleanly. The master's tools are handmade. Every edge matching the measurements you took at the start, and refined millimeter by millimeter.

Magnolia is the traditional choice: it draws moisture away from the steel to prevent damage, and holds its shape across years.

To finish a complete saya, it can take several weeks by a professional. While you may not be able to complete an entire saya, you’ll be able to take home a small souvenir.
