T10 Carbon Steel Katana with Real Hamon, Bronze Snake Tsuba in Black-Red Koshirae

The blade is forged from T10 carbon steel and finished with a visible real hamon line - the boundary between hardened edge and softer spine runs in a flowing natural pattern along the polished nagasa. The chrome-finish surface catches light cleanly, and the full tang construction runs the entire length from tip to handle core, giving the piece structural integrity throughout.

The tsuka is built on a red glitter-lacquered wooden handle core wrapped in genuine white ray-skin (samegawa), then finished with black cord ito in a traditional diamond-pattern wrap. The contrast between the deep black ito, the textured white samegawa diamonds showing through, and the red-accented core beneath creates the signature black-red color scheme visible at a glance. For collectors interested in similar color combinations, the Darkred T10 Carbon Steel Katana collection offers additional options in this palette.

The bronze snake tsuba is the centerpiece of this koshirae. Cast in open-work relief, the serpent design wraps the circular guard with scaled texture and fine detail work. The bronze tone carries through to the matching fuchi (collar) and kashira (pommel cap), giving the fittings a warm, aged-gold visual consistency against the dark handle.

The black hardwood lacquer saya delivers a high-gloss finish that pairs directly with the black ito and black sageo cord. The sageo is knotted in the traditional style at the kurigata, completing the overall koshirae presentation. The lacquer surface is smooth and even, with no visible grain - consistent with a sealed hardwood base.

At 41 inches overall and 3 lbs, this katana is sized for wall display or collection shelving. The package ships at 43 x 4 x 4 inches and 4 lbs. Sword stand not included.
