Product Details

The blade on this katana is ground from T10 carbon steel and finished by hand to produce a clean, mirror-polished edge line running the full length of the nagasa. A visible hamon traces the boundary between edge and spine, the result of the differential heat treatment process used during forging. The full-tang construction carries the steel through the handle core, giving the piece stable weight distribution from tip to pommel. For collectors exploring Natural T10 Carbon Steel Katana options, this build represents a detailed koshirae example at an accessible entry point.

The tsuka is wrapped in black cotton cord laid in a tight diagonal cross pattern over a red rayskin foundation. Knot paper is layered beneath the wrap to build structure and keep the binding from shifting, a detail visible where the cord meets the fuchi. The handle ends with a bronze kashira that picks up the warm antique tone carried across the rest of the fittings.

The tsuba is cast in bronze with a circular profile and features a raised tomoe motif - the classic three-comma emblem associated with Japanese heraldry. The embossed surface has a textured, aged appearance that reads clearly against the polished blade collar. Seppa on both sides of the tsuba maintain alignment and add to the layered hardware assembly.

The saya is crafted from hardwood finished in gloss black lacquer. Four gold-tone tomoe medallions are evenly spaced along the scabbard face, each stamped with the same three-comma design as the tsuba. This repetition of the tomoe motif across tsuba and saya ties the entire piece together visually. A black-and-red braided sageo is hand-knotted at the kurigata, mirroring the tsuka wrap colors and completing the two-tone color scheme. Collectors drawn to this aesthetic may also find the Black Dragon Katana Sword collection worth exploring.

At 41 inches overall and 3 lbs, this katana ships in a 43 x 4 x 4 inch package at a shipping weight of 4 lbs. The piece is finished as a full koshirae replica - blade, handle, tsuba, and saya all included. Stand or display holder is not included.
