Manganese Steel Katana Red Blade with Koi Tsuba - Black Cord Handle, Red Lacquer Saya

The blade on this katana is ground from high manganese steel and given a bold red finish that runs the full length of the nagasa. A genuine hamon line traces the edge - the irregular, flame-like temper pattern visible along the lower portion of the blade is a defining feature of this piece. The 41-inch overall length and the pronounced curvature of the blade give it the classic silhouette of a traditional katana form.

The full-tang construction extends the steel core through the entire length of the tsuka, providing the kind of structural continuity expected in a properly assembled katana. The handle is wrapped in black cotton ito using a traditional diagonal diamond pattern over a white PU samegawa underlayer. The contrast between the black wrapping and the bright samegawa creates the characteristic open-diamond pattern visible along the handle.

The tsuba is cast from silver-toned alloy and features an intricate koi fish and crashing wave design in high-relief scrollwork. Two mirrored koi figures emerge from stylized waves, filling the oval guard face with layered detail. The silver finish of the tsuba and menuki fittings ties directly into the white hamon line on the blade, creating a cohesive metallic accent thread across the piece.

The saya is crafted from hardwood with a deep red lacquer finish that mirrors the blade's color. The surface carries a smooth gloss that catches light along its curve. Black sageo cord is tied at the kurigata with a short tassel finish, adding a traditional accent against the red lacquer. This Red Hardwood Japanese Samurai Swords collection features additional pieces in this same saya style.

With an overall length of 41 inches and a shipping weight of 5 lbs, this katana arrives as a complete koshirae assembly - blade, handle, tsuba, and saya. The red-and-black color scheme, koi guard motif, and visible hamon make this a strong addition to any themed display or katana collection. Sword stand is not included.
