T10 Carbon Steel Full Tang Katana with Hamon Blade - Black Glitter Saya & Gold-Black Tsuba

The blade of this katana is forged from T10 carbon steel - a high-carbon tool steel prized for its hardness and edge retention. A genuine hamon temper line runs along the edge, the result of a traditional differential heat-treatment process that leaves a distinct visual boundary between the hardened edge and the softer spine. The chrome-polished surface is hand-finished to bring out the hamon's detail and the subtle bo-hi groove relief, giving the blade both visual depth and structural character. At 40.55 inches overall and 2.8 lb, it carries the proportions of a traditional katana without sacrificing balance in hand.

The tsuka is wrapped in black cotton ito over genuine white samegawa (ray skin). The tight diamond-pattern braid exposes the white rayskin at each opening, creating a clean black-and-white contrast that mirrors classic koshirae aesthetics. The wrap is firm and consistent end to end, with the menuki seated securely beneath the ito at both the ura and omote positions - visible as the white diamond accents along the handle in the product image.

The tsuba is the defining accent piece of this build. Finished in gold with a black stippled field of raised dot relief, it carries a copper-toned oval sekigane at center. The fuchi and kashira are finished in coordinating dark metal to frame the tsuka cleanly. This gold-black color scheme sets the guard apart from standard iron or silver fittings and gives the sword a warmer, richer visual tone at the crossguard. Collectors looking to explore more elaborate guard designs can browse our Black Tiger Katana series for additional koshirae configurations.

The saya is where this katana makes its most distinctive visual statement. Constructed from hardwood and coated in black lacquer, the scabbard is finished with a multicolor glitter overlay - fine particles of blue, orange, and gold are suspended across the entire surface, catching ambient light and shifting in tone depending on the viewing angle. No two sayas will read identically. A black sageo cord is tied at the kurikata with a traditional loop knot and drapes cleanly to the kojiri, maintaining the koshirae's cohesive all-black cord palette.

This katana is assembled as a complete koshirae set and is well-suited for collectors interested in T10 steel construction and traditional Japanese sword furniture.
