Manganese Steel Black Blade Katana with Red-White Tsuka Wrap - Koshirae Style Replica

The blade on this katana is forged from manganese steel and finished in a deep black tone that runs the full length of the 40.5-inch overall profile. A visible hamon line traces the edge, creating a bright contrast against the darkened flat - the result of hand-finishing work rather than a printed or painted effect. Running the entire length through the handle as a full tang, the blade also carries a wave engraving pattern along the spine that adds a raging-fire visual energy unique to this design. Spine thickness measures 0.28 in with a 1.26 in blade width, giving the piece a solid, well-proportioned feel at 3.2 lb.

The tsuka is wrapped in red ito cord over a white PU ray-skin (samegawa) base, forming crisp diamond-shaped windows in a tight, even pattern. This red-and-white combination is one of the most visually arresting elements of the build and connects to the broader Red Handle Katana aesthetic tradition. Alloy fittings secure the wrap at both ends, with a gold-tone menuki tucked beneath the ito for an authentic koshirae-style detail.

The tsuba is cast iron in a rounded oval form, finished in black with an ornate scroll relief pattern across the surface - intricate floral and foliate motifs that reward close inspection. The seppa and habaki fittings transition cleanly between tsuba and blade, maintaining the tight fit expected of a properly assembled koshirae mounting.

The saya is constructed from hardwood with a premium natural lacquer finish in gloss black - smooth, even, and free of visible grain texture under the coating. A braided sageo cord in black and red wraps the kurikata with a functional knot secured by an amber-toned bead, adding a small but distinctive handcrafted detail to the scabbard. This black-on-black saya and blade combination, offset by the red cord accents, gives the piece a cohesive and visually bold presentation.

With overall dimensions of 40.5 in length, 1.26 in width, and 0.28 in spine depth, this katana sits at a full-size replica scale appropriate for display mounting, costume use, or kata demonstration. It is part of the broader Traditional Japanese Sword category - a well-appointed koshirae-style piece that balances dramatic visual design with solid construction detail. Sword stand not included.
