T10 Steel Tachi Katana with Real Hamon in Red Lacquer Saya - Gold Chrysanthemum Tsuba, Brown Cord Handle

The blade is forged from T10 high-carbon steel and finished with a traditional heat-treat process that produces a genuine hamon temper line visible along the edge. The chrome-polished flat catches light cleanly, while the hamon traces an organic, wave-like boundary between the harder edge steel and the softer spine - the defining mark of authentic differential tempering. The full-tang construction keeps the blade firmly anchored through the handle for long-term structural integrity.

The tsuka is wrapped in brown cord tsuka-ito over a white ray-skin (samegawa) foundation, with the classic diamond lozenge pattern running the full length of the grip. White menuki accents are set beneath the wrap at the traditional positions. The fittings - seppa, habaki, and koiguchi collar - are finished in bright gold-tone alloy, tying the handle assembly to the saya hardware in a unified color story.

The tsuba is a standout element: a large, round gold-finished alloy guard bearing a deeply sculpted chrysanthemum (kiku) relief design. The chrysanthemum is one of Japan's oldest imperial emblems, and its use here grounds the sword aesthetically in classical koshirae tradition. A small engraved kamon roundel on the fuchi collar reinforces the period-style detailing.

The saya is crafted from hardwood finished in a deep red lacquer - the rich, saturated crimson provides a striking visual contrast against the chrome blade and gold fittings. The gold braided sageo cord is looped and secured to the kurikata in a traditional tying configuration, adding texture and color depth to the scabbard presentation. This combination of red, gold, and brown makes the sword immediately recognizable as a high-visual-impact Japanese Odachi or tachi-style koshirae piece.

At 41 inches overall and 3 lb, this sword is sized and balanced for horizontal wall display or vertical stand mounting. The complete koshirae - red saya, gold sageo, chrysanthemum tsuba, brown ito, and gold hardware - comes fully assembled. Sword stand not included.
