Manganese Steel Katana with Real Hamon, Green Ito & Flower Alloy Tsuba - Collectible Replica

The 28.74-inch nagasa is forged from manganese steel and heat-treated to 62 HRC, producing a visible hamon line that traces the differential hardening along the edge. A dragon engraving runs along the blade surface, adding a layer of artisan detail to the hand-finished, sharpened chrome-finish steel. The full-tang construction keeps the blade anchored through the handle for structural integrity across the entire 40.55-inch length.

The tsuka measures 10.62 inches and is built over a real black rayskin (samegawa) base, whose nodular texture locks the wrap firmly in place. Green ito is applied in a traditional diamond-cross pattern over the samegawa, with cream-colored menuki accents visible between the wraps - matching the green-and-white color theme carried through the rest of the koshirae fittings.

The brown alloy tsuba features a raised floral motif with gold-tone highlights on the relief work - chrysanthemum and botanical forms that frame the blade opening. The oval guard sits flush against the habaki and gives the sword its defining visual character. For collectors drawn to nature-themed fittings, this tsuba is the focal point of the entire piece.

The saya is shaped from hardwood and finished in a matte black lacquer coat, 29.92 inches in length. A green-and-white sageo is bound at the koiguchi with a formal knot, an amber bead accent visible at the cord crossing. The high-contrast combination of matte black lacquer against the green-white cord is consistent with the handle's color palette and gives the set a cohesive, finished appearance.

Total weight is 2.8 lb. with shipping weight of 3.3 lb. At 40.55 inches overall, this koshirae-style replica is sized to full katana proportion and displays cleanly on a horizontal sword stand or mounted rack. Every fitting - from the floral tsuba to the lacquered saya - reflects the traditional assembly of a Japanese sword in full koshirae dress.
