Traditional Hand-Forged Full-Tang Clay-Tempered T10 Steel Katana — Differentially Hardened & Hand-Polished

Specifications

Dimensions

The name Suiha (翠波) draws its meaning from two characters: 翠, the jade-green of kingfisher feathers and deep water, and 波, the wave that never stops moving. Together they describe a blade the color of the ocean at its most unreadable depth — calm on the surface, restless underneath.

This katana is clay-tempered by hand in T10 high-carbon steel, a process that leaves behind a genuine hamon along the edge — no two blades develop the exact same line. The tsuba, menuki, and fittings are cast in aged bronze, giving the piece a weathered, heirloom quality rather than a polished, factory-new look. The tsuka is wrapped in real rayskin over a solid wood core for a secure, traditional grip, and the saya is carved from solid wood and finished in Suiha's signature emerald green.

Suiha is built for collectors who want a piece with real presence on a display stand, and for enthusiasts who appreciate traditional materials and construction. Each sword is made to order, so please allow approximately two weeks for crafting before it ships.

Care and maintenance

Wipe the blade after handling to remove oils and moisture, and apply light choji oil for long-term storage. Maintain fittings and saya with dry cloths; avoid abrasive cleaners that can alter patina or rayskin. Because each sword is hand-forged from custom carbon steel, follow traditional cleaning and oiling routines to preserve the hamon and blade integrity.

Handmade Variations

Each sword is handmade, so no two swords are exactly alike. Slight variations in finish, natural material grain, and measurements are part of the handcrafting process. Product photos are representative, and listed dimensions are approximate.
