Ryuza — the dragon’s throne — and the dragon coils through every fitting on this sword. The seat of the name is the steel itself: a top-class sanbon sugi hamon, the three-cedar wave that rolls in clusters of three peaks down the edge, drawn out of the quench by skilled differential hardening rather than acid or print.
Forging & Steel
The blade is forged from high-carbon T10 tool steel, clay-tempered for a hard, wear-resistant edge over a tougher core. The sanbon sugi line is a signature of careful heat treatment: the regular three-peak rhythm is far harder to control in the quench than a plain wave, and it only forms cleanly when the clay is laid with a steady hand. The steel rewards serious martial artists with edge retention that survives repeated cutting, and the hard edge over a softer core gives the blade both bite and shock tolerance. It is sharpened and ready for use.
Fittings
The tsuba is copper carved into the form of a dragon — strength and courage rendered in metal, doubling as the balance point and hand guard. The saya is lacquered wood, engraved and painted with a majestic dragon motif and finished in a black sageo, so the creature on the guard is answered by the creature on the scabbard. The tsuka is wrapped in genuine white shagreen with a copper menuki kit, locked by two bamboo mekugi for a rigid, rattle-free assembly.

Is it battle-ready?
Yes. The Ryuza is a sharpened, full-tang cutting katana for tatami and serious practice, not a wall-hanger. It sits among our master-tier katana alongside the Pikokku and the Nihon.
