T10 Carbon Steel Katana with Red Dragon Saya - Black-Red Tsuka, Hamon Blade, Koshirae

The blade of this katana is forged from T10 carbon steel and clay tempered to produce a genuine hamon - the undulating line along the edge where the hardened cutting zone meets the more resilient spine. Under light, the polished chrome-finished surface reveals the hamon's contours clearly, reflecting the traditional heat-treatment process built into every hand-finished piece in this line. Blade length runs 40.55 inches overall, with a width of 1.259 inches and a spine thickness of 0.275 inches.

The tsuka is built over a full-tang core, wrapped first in real red samegawa (ray skin) and then finished with black cotton cord in a traditional diamond-pattern wrap. Red ray skin peeks through the gaps between each wrap segment, creating a striking black-red contrast along the entire handle length. Gold-toned menuki accents are set beneath the cord at intervals, adding depth to the grip's visual layering.

The tsuba is a black cast-iron piece with raised dragon relief carving across its surface - dense, intricate texture that reads clearly even at a distance. A gold-tone habaki collar sits between the tsuba and blade, providing a clean material transition and locking the guard in place within the koshirae assembly. The sageo hanging cord is black, coordinating with the tsuka wrap and tsuba.

The saya is crafted from hardwood and finished in high-gloss red lacquer, with large-scale black dragon artwork hand-applied across the full length of the scabbard. The imagery is bold and graphic - dark swirling forms against the vivid red base, with scattered gold-tone distressing in the upper section near the koiguchi. A black sageo cord is knotted at the kurikata, completing the traditional mounting. This Purple And Red Katana Sword collection offers additional red-toned koshirae options worth comparing.

At 2.8 lb and 40.55 inches overall, this katana sits within standard full-size proportions and is designed as a collector koshirae piece in the traditional style. The red-black-gold palette is consistent across every component - saya, tsuka, tsuba, and habaki - making it a cohesive set rather than an assembled mix. Collectors exploring Curved Katana Sword options will find this piece representative of the curved nagasa format with a fully matched koshirae.
