Product Details

The blade is forged from T10 carbon steel, a high-carbon tool steel known for its edge retention and the clarity of its hamon temper line. The visible wavy hamon runs continuously along the 40.55-inch blade, marking the boundary between the hardened edge and the tougher spine - a defining characteristic of traditional Japanese sword construction. The chrome-finished surface is mirror-polished to highlight the hamon's contrast and the gentle curvature of the blade profile.

The tsuka is wrapped in orange cotton-cord ito over a black PU samegawa base, following a classic diamond-pattern wrap that leaves the samegawa peeking through at each crossing point. Black menuki figures are seated beneath the ito at both grip positions, adding dimensional texture and visual rhythm to the handle. The overall effect is a warm, high-contrast handle that reads clearly against the blade's silver tone.

The tsuba is crafted from iron in a circular form with a chrysanthemum motif rendered in gold against a flat black ground. The black-and-gold color pairing gives the guard a structured, formal character consistent with koshirae-style mounts. The fuchi collar transitions cleanly between tsuba and tsuka, maintaining the overall assembly's tight fit.

The saya is constructed from hardwood lacquered in deep burgundy, with cream-gold diagonal stripe inlays wrapping the length of the scabbard in a bold geometric pattern. A brown sageo cord is tied at the kurigata, providing both a practical retention cord and a grounding earthy tone that complements the warm palette of the full piece. Collectors interested in related scabbard styles can browse the Darkred Saya Katana collection for additional options in this finish direction.

Overall dimensions are 40.55 in length, 1.259 in blade width, and 0.275 in blade thickness, with a total weight of 2.8 lb. The full-tang construction runs the blade steel through the handle for structural integrity. This piece is finished in full koshirae style - tsuba, fuchi, kashira, and sageo all coordinated - making it a cohesive addition to any Japanese sword collection. For collectors focused on swords with distinctive scabbard finishes, the Red Leather Scabbard Japanese Samurai Swords collection offers complementary display options.
