Product Details

The blade is forged from Damascus steel, delivering the layered grain pattern characteristic of folded construction. A genuine hamon runs along the edge - produced through the differential hardening process - creating a visible temper line that shifts in the light. The hand-finished edge shows careful attention at the tip, with a clean, consistent grind across the 40.16-inch overall length. Blade width measures 1.26 inches with a thickness of 0.27 inches, and the complete sword weighs 3.3 lbs. Collectors looking for Damascus construction will find this listed alongside other examples in our High Carbon Damascus Steel Katana collection.

The tsuka is built on a full tang core and wrapped in genuine red samegawa - the textured ray skin that has been standard in traditional Japanese sword furniture for centuries. Over the samegawa, black ito is applied in a classic diamond-pattern wrap, pulling tight against the underlying skin and producing the red diamond windows that show through between crossings. The result is a high-contrast black-and-red handle that photographs well and holds its wrap over time.

The tsuba is cast in copper and finished with silver gilding across an ornate scroll design. The guard face is rendered in black and white with deeply carved floral and scroll motifs - the relief work is sharp-edged and catches light differently depending on the viewing angle. A small copper habaki seats the blade cleanly at the guard, maintaining centering through the assembly.

The saya is constructed from a wood core and fully wrapped in black pearl rayskin - the same material used on the tsuka, here presenting in fine-grain black across the scabbard's full length. Koiguchi and kojiri are fitted in real horn, giving the open and closed ends a natural, dense finish that contrasts with the dotted texture of the rayskin. A black-and-white braided sageo is tied at the kurikata, completing the koshirae-style presentation.

This katana is a full koshirae replica piece - 40.16 inches overall, 3.3 lbs, with Damascus steel blade, real samegawa and horn fittings, and silver-gilded copper tsuba. It ships in packaging measuring 42 x 4 x 4 inches at 5 lbs. Sword stand is not included. For more options with matching saya construction, see the Black Rayskin Saya Japanese Samurai Swords collection.
