1045 Carbon Steel Ninjato in Black Hardwood Saya with Ornate Scroll Alloy Tsuba - Koshirae Style

The blade on this ninjato is forged from 1045 carbon steel, ground to a 27.5-inch length and heat-treated to 58 HRC. The chrome-polished surface gives the straight blade a mirror-bright appearance, and the hand-finished edge runs cleanly to a sharp tip. No hamon is present - the blade delivers a uniform, polished look from spine to edge. If you're exploring options across this steel grade, the 1045 Ninja Sword collection covers a range of configurations worth comparing.

The full tang extends through the entire 10.25-inch tsuka, keeping the blade and handle locked together without flex. The handle core is wrapped in white polyurethane leather samegawa, then finished with a traditional black cord wrap in a diamond-pattern binding that exposes the white underlayer at regular intervals - creating the stark black-and-white contrast visible throughout the grip.

The alloy tsuba is cast in an ornate scroll pattern and finished in a dual gold-and-silver tone. As seen in the detail images, the floral and scrollwork relief is well-defined, with the gold habaki collar seating cleanly against the guard. The overall koshirae fittings carry a consistent classical aesthetic without over-stylizing the design.

The saya is built from hardwood and finished in a black piano lacquer coat, producing a high-gloss, smooth surface along all 27.5 inches of the scabbard. A black sageo cord is looped through the kurigata, keeping the presentation uniform from saya to handle. For more options in this finish style, the Blackwood Scabbard Ninjato collection offers additional variations.

Overall length comes in at 40.5 inches with a total weight of 3.5 lbs, balanced for display or koshirae-style presentation. The koshirae assembly - from the polished blade to the lacquered saya - makes this a well-put-together collectible piece with cohesive black-and-gold detailing throughout.
