Product Details

The blade is forged from full-tang 1045 carbon steel, running uninterrupted from tip through handle for maximum structural integrity. At 40.5 inches total length and 3.17 pounds, the chrome-polished nagasa carries a consistent 1.29-inch width with a gentle curvature that catches light evenly along its length. Explore more options in our 1045 Carbon Katana collection.

The tsuka is built over a hardwood core wrapped in PU white samegawa, then finished with tightly applied black cotton ito in the traditional diamond hishi-gumi pattern. The white samegawa shows cleanly through each opening, creating a sharp two-tone contrast against the black wrapping that is both visually defined and functional in grip security.

The tsuba is cast alloy in a deep gunmetal-black finish, engraved with a flowing wave and cloud motif. The relief carving is detailed and dimensional - curved lines layered to suggest rolling surf - giving the fitting a genuine artisan quality at the transition point between blade and handle.

The saya is constructed from hardwood and finished in piano-lacquer black, producing a high-gloss mirror surface with clean depth. A black sageo cord ties at the kurikata, and the overall koshirae styling keeps every component in a unified black palette.
