Product Details

The blade on this katana is forged from Damascus steel, revealing a dark red surface threaded with the folded multi-layer grain patterns characteristic of the material. A visible hamon traces the edge from machi to kissaki, and the blade geometry - 40.5 in overall, 1.26 in at the widest point - delivers the proportions expected of a traditional katana in full koshirae dress. The layered steel construction, finished to expose its natural color variation, gives this piece the depth that collectors in the Red Blade Damascus Steel Katana category look for.

The tsuka is built with a black cotton ito wrap laid over white PU samegawa in the classic diamond (hishi-gumi) pattern. Each wrap segment is evenly spaced, and the underlying ray-skin texture shows through at the diamonds, giving the handle visual rhythm as well as grip texture. Alloy fittings at the fuchi and kashira complete the handle assembly.

The tsuba is black iron with an ornate scroll motif engraved across its face. Gold and silver gilded detail work sits within the design, creating a layered contrast between the dark iron ground and the metallic accents. The rounded square silhouette is a classic koshirae form that frames the habaki cleanly at the blade-handle junction.

The saya is hardwood lacquered in gloss black, with a marble-style vine pattern worked into the finish. The design covers the full length of the scabbard and reads differently depending on the light angle. A braided blue-and-gold sageo is knotted at the koiguchi in a traditional wrap, adding the most saturated color in the piece and tying the overall palette together. Collectors interested in this style of layered Damascus work can explore the full Multi-colored Damascus Steel Katana range for related pieces.
