T10 Clay Tempered Katana with Real Hamon in Black Piano Lacquer Saya - Gold Copper Tsuba Full Tang Sword

This katana features a 28.74-inch full tang blade forged from T10 carbon steel and finished through traditional clay tempering. The differential hardening process produces a genuine hamon - a wavy temper line clearly visible along the spine side of the blade. Hardened to 58 HRC, the steel offers a strong balance of edge retention and resilience. The chrome-toned blade surface carries subtle grain patterns that catch light at different angles.

The 10.23-inch tsuka is built on a hardwood core wrapped in authentic white samegawa (ray skin), then bound tightly with black cotton ito in a traditional diamond pattern. Gold-toned menuki accent the handle beneath the wrapping, and the kashira at the pommel matches the dark overall theme. This setup creates a secure, comfortable hold while keeping the visual profile clean and understated.

At the center of the sword sits a real copper tsuba finished in gold tones, featuring detailed relief work with traditional Japanese motifs. The guard's round profile with carved openwork adds depth and character, serving as a visual anchor between blade and handle. This is a standout piece for anyone drawn to our wider T10 Steel Katana collection.

The 30.7-inch black hardwood saya is coated in piano lacquer, giving it a smooth, glossy finish with excellent scratch and wear resistance. Tomoe-styled kurikata and kojiri details line the scabbard, while a black sageo cord is tied at the mouth. Inside, knot paper lines the interior for added blade protection during storage. This sword pairs well with other pieces in the Black Samurai Sword collection.

Measuring 41 inches overall and weighing 4.4 lbs, this katana carries serious presence on a wall mount or sword stand. Every component - from the clay tempered T10 blade to the copper tsuba and lacquered saya - is hand-assembled, making it a cohesive collectible that rewards close inspection.
