Product Details

The blade is forged from T10 carbon steel and ground to a full tang construction spanning the sword's entire 40.55-inch length. Heat-treated to 62 HRC, the 28.74-inch nagasa displays a genuine hamon - the visible temper line along the edge that emerges from differential hardening. The chrome-finished surface contrasts cleanly with the undulating hamon pattern, making the blade as visually detailed as it is structurally sound.

The 10.62-inch tsuka is built over an authentic white rayskin (samegawa) foundation, then hand-wrapped in brown cotton ito using a traditional diamond-pattern braid. The white samegawa nodes show through the gaps in the wrap, creating the classic alternating texture associated with Japanese koshirae construction. The brown cord color runs consistently from the kashira down to the tsuba collar.

The black alloy tsuba is finished in a geometric open-cut style - a circular form with intersecting lattice cutouts that reduce visual weight while keeping a strong structural profile. Against the ivory-toned habaki and the dark brown tsuka, the black tsuba creates a sharp tonal transition that anchors the sword's color scheme.

The saya is shaped from hardwood and finished in a deep dark red matte lacquer. The surface carries a fine speckled texture across the lacquer layer, adding visual depth beyond a flat solid color. A brown sageo cord is knotted at the kurigata with a decorative tassel finish. Saya length is 29.92 inches, fitting the blade with standard clearance.

Total assembled length is 40.55 inches with a blade width of 1.259 inches and spine thickness of 0.275 inches. The sword weighs 2.8 lbs, balancing usability with display presence. This is a koshirae-style piece built with traditional material choices - rayskin, lacquered hardwood, and alloy fittings - suited for collectors who prioritize authentic construction details.
