Katana – T10 Clay-Tempered Leaf Hamon Blade with Solid Iron Mounts | Kanemasa

【Overview】

This katana is crafted from high-hardness T10 steel and traditionally clay tempered to reveal a distinctive leaf-pattern hamon.

Named Kanemasa, this sword emphasizes understated strength and classical balance, combining authentic materials with solid iron mountings for a refined, martial presence.

【Blade & Craftsmanship】

The blade is hand-forged from T10 high carbon steel, valued for its excellent hardness and edge stability.

An exclusive clay tempering process produces a natural leaf-style hamon, while a full-length bo-hi (fuller) improves balance and handling.

Final edge shaping and polishing are completed entirely by hand to ensure consistent sharpness and clarity.

【Design & Mountings】

All fittings, including the tsuba, fuchi, and kashira, are crafted from solid iron rather than alloy.

Hand engraving adds subtle detail while preserving a restrained, traditional aesthetic and a satisfying, weighty feel in use.

【Handle & Saya】

The handle is wrapped with genuine ray skin (samegawa), providing secure grip and an authentic tactile experience.

The saya is made from natural hardwood and finished with a refined lacquer coating, complemented by a premium sageo cord.

【Performance】

With hardness reaching approximately 62 HRC, this katana delivers excellent cutting performance and durability.

It cleanly cuts bamboo and plastic targets while maintaining edge integrity and overall balance.
