Product Details

The blade on this katana is hand-forged from T10 carbon steel, with a visible hamon line running along the edge that reflects the hand-finished tempering process. At 40.55 inches overall with a 1.259-inch width and 0.275-inch spine thickness, the chrome-polished nagasa carries a classic curvature suited to the koshirae style. If you're exploring T10 Carbon Steel Japanese Samurai Swords, this piece demonstrates what a properly finished T10 build looks like in full koshirae dress.

The tsuka is wrapped in brown ito over real white samegawa, with diamond-shaped menuki peeking through at regular intervals along the grip. The wrap pattern and ivory-toned menuki contrast cleanly against the warm brown cord, giving the handle strong visual definition and a secure grip surface.

The tsuba is copper-bodied in black and gold, built around a samurai theme. The face shows a warrior figure in raised relief with gold detailing, surrounded by wave and cloud engravings across the black-finished plate. It reads as a true koshirae piece - the kind of fitting that anchors the sword's identity as something designed to be looked at closely.

The saya is dark red hardwood finished in natural lacquer, fitted with real horn at the koiguchi and kojiri. A black-gold braided sageo cord wraps the upper saya in a layered koi-knot pattern, adding texture and tying the black-gold color story from the tsuba down to the scabbard. For collectors drawn to Old Samurai Sword aesthetics, the dark red lacquer and horn fittings bring that period-correct detail without compromise.

Total weight is 2.8 lbs, shipping weight 3.3 lbs, packaged at 42.9 x 3.9 x 3.5 inches. The full tang construction runs uninterrupted through the tsuka, giving the assembly structural integrity across fuchi, habaki, and kashira. Every fitting - finished in coordinated black and gold tones - works together to present a unified koshirae set rather than a collection of mismatched parts.

  • T10 carbon steel blade hand-forged with a visible hamon line along the edge, delivering refined edge retention and a polished chrome finish across the 40.55-inch overall length.
  • Full tang construction runs the blade through the brown real white samegawa tsuka, wrapped in brown ito with diamond-pattern menuki, providing solid balance at 2.8 lbs total weight.
  • Black-gold copper tsuba features a hand-finished samurai theme relief - a warrior figure with gold accents set against a black ground with wave and cloud engravings on both faces.
  • Dark red hardwood lacquer saya is fitted with real horn koiguchi and kojiri, secured by a black-gold braided sageo cord wrapped in a traditional koi-knot pattern along the upper saya.
  • Koshirae-style fittings throughout - fuchi, kashira, and habaki finished in coordinated black and gold tones that unify the brown handle, dark red saya, and chrome blade into one cohesive set.
