T10 Clay Tempered Katana with Real Hamon in Black Lacquer Saya - Gold Dragon Tsuba, Red Samegawa

The blade is forged from T10 carbon steel and clay tempered to approximately 60 HRC, a differential hardening process that produces a naturally occurring hamon - the undulating line of crystalline contrast running along the edge. At 28.3 inches in nagasa and 1.26 inches wide, the blade carries a polished chrome finish that makes the hamon line clearly visible under light.

The tsuka is 10.2 inches long and built over a full-tang hardwood core. Red samegawa - genuine ray skin - covers the grip base, and black cotton cord is wrapped tightly in a traditional hishi-gumi diamond pattern over it. A silver-toned kashira caps the pommel, providing a clean finish to the wrap.

The tsuba is cast from alloy and finished in gold tone, featuring an openwork dragon design with gold and silver surface detailing. The square-ish form with rounded corners sits cleanly between blade and handle, anchoring the visual transition from polished steel to the black-and-red tsuka.

The saya is shaped from hardwood and finished in piano lacquer, producing a deep, reflective black surface that runs 30.3 inches. The upper section near the koiguchi is wrapped in red ray skin, directly echoing the samegawa on the handle. Black sageo cord is knotted at the kurikata, completing the two-color contrast that defines this katana's aesthetic.

Overall length is 40.5 inches and the piece weighs 2.65 lbs - proportions that reflect traditional katana geometry. The combination of clay-tempered T10 steel, handcrafted fittings, and the black-lacquer-and-red color scheme makes this a cohesive piece for collectors who value both construction and visual character.
