Product Details

The blade is forged from T10 carbon steel and clay tempered to produce a clearly defined hamon line running along the edge. The hand-finished chrome surface catches light evenly across the curve of the nagasa, and the full tang construction ensures the steel runs continuously from tip through the length of the tsuka. At 40.5 inches overall with a 1.26-inch width and 0.275-inch spine thickness, the proportions follow classic katana geometry without deviation.

The tsuka is built over a hardwood core and wrapped in black cotton cord, laid in a traditional hishigami diamond pattern over red PU samegawa underneath. Red menuki are set into the wrap at both lobes, adding color contrast that pulls the black-and-red palette together at close range. The handle construction is consistent with Multi-colored Katana builds that prioritize visual detail alongside structural soundness.

The tsuba is cast in black alloy and shaped in an ornate scroll pattern - an open lattice design with interlocking curves that frames the habaki and gives the transition between blade and handle a strong visual anchor. The gold-toned habaki and fuchi provide metallic contrast against the black guard, keeping the hardware from reading as flat or uniform.

The saya is shaped from hardwood and finished with a premium red natural lacquer that produces a deep, speckled gloss across the surface. Up close, the lacquer shows texture variation rather than a flat coat - areas of the finish show fine grain and depth consistent with a layered application. The sageo is red cord, tied at the kurigata in a square knot with hanging ends. For collectors focused on the saya finish specifically, this piece fits well within the Red Hardwood Japanese Samurai Swords category.

Overall length is 40.5 inches, width 1.26 inches, spine thickness 0.275 inches, and item weight 3.17 lb. The koshirae-style fittings across tsuba, habaki, fuchi, and kashira are coordinated in black and gold tones, and the red-black-chrome color scheme holds together across every component from tip to saya end.

  • T10 carbon steel blade is clay tempered and hand-finished, producing a visible hamon line along the edge that reflects traditional Japanese forging discipline.
  • Full tang construction runs the entire length of the tsuka, providing structural integrity across the 40.5-inch overall length and 3.17 lb balanced profile.
  • Black alloy tsuba features an ornate scroll cutout pattern - the open lattice design adds visual depth while keeping the koshirae style cohesive and refined.
  • Tsuka is wrapped in black cord over red PU samegawa, with red menuki accents woven into the hishigami pattern for a striking black-red color contrast.
  • Red hardwood saya is finished with premium natural lacquer and secured with a red sageo cord - the speckled gloss finish gives the scabbard a layered, dimensional appearance.
