Product Details
The blade is the defining feature of this ninjato replica - forged from high manganese steel and finished in a deep red that covers the flat of the nagasa from spine to just above the hamon line. That jagged, wave-pattern hamon in white runs the full length of the blade, creating a sharp visual contrast against the red finish. The edge itself is hand-finished to a precise bevel, and the blade tapers to a clean kissaki. Full-tang construction means the steel extends uninterrupted through the handle for solid, balanced handling. At 43.3 inches overall and 3.08 lbs, it carries real presence without being unwieldy. If you're exploring the broader range of red-finished blades, the Red Metal Sword collection offers additional options in this aesthetic.
The tsuka is built around a black textured foundation wrapped tightly in black cord using a traditional diamond-pattern braid. The wrap is even and firm, with no loose sections. A black alloy kashira caps the pommel end, cast with subtle relief detailing visible in close inspection. The fuchi at the blade end matches in finish and tone, keeping the hardware cohesive.
The tsuba is a circular black alloy guard with a clean, plain profile - no elaborate motifs, just a well-proportioned form that sits flush against both the saya koiguchi and tsuka fuchi. Its matte black finish blends seamlessly into the overall monochrome koshirae without drawing attention away from the blade's red finish.
The saya is constructed from hardwood with a black lacquer finish and wrapped in black PU leather in the same diamond-texture pattern as the tsuka. A braided black sageo cord with three copper-tone beads ties at the kurigata, adding one of the only non-black accent details on the sword. The fit between blade and saya is snug, with a clean draw and secure retention. For collectors interested in this build quality and style, the Manganese Sword collection covers additional manganese steel options.
Overall dimensions: 43.3 inches in length, 1.26 inches in width, 0.275 inches in height, weighing 3.08 lbs. Ships in a 47 x 4 x 4 inch package at 5.5 lbs. Sword stand not included. This piece works equally well as a display centerpiece or a collector's addition to a Japanese sword koshirae set.
