Kokushibo Ninjato in Manganese Steel with Crackle Hamon, Black Lacquer Saya & Dragon Kojiri

The blade on this ninjato is forged from manganese steel and hand-finished to a bright chrome polish, with a dramatic crackle-pattern hamon running the full length of the nagasa. Near the habaki, a dragon engraving adds depth and character that references Kokushibo's moon-breath aesthetic from Demon Slayer. The straight, ninjato-profile blade measures 41 inches overall and carries a solid 4 lb heft that makes the sword feel substantial in hand. Each blade is individually worked by experienced swordsmiths, so the hamon line and surface texture carry slight natural variation from piece to piece.

The tsuka is built full-tang and wrapped in black cord using a traditional diamond cross pattern over PU black samegawa. A small gold-toned menuki is set beneath the wrap at the mid-grip, visible at the intersection points. The plain black alloy tsuba keeps the transition between blade and handle minimal - no ornamental cutouts, just clean geometry that reinforces the dark, unified koshirae style.

The saya is shaped from hardwood and finished in multiple coats of premium natural lacquer, producing a deep, high-gloss black surface. A silver-toned kojiri cast with a detailed dragon relief secures the tip, while the koiguchi end features a circular mon medallion in white-on-black - a direct visual nod to Kokushibo's family crest. Black sageo cord is tied at the kurikata for traditional carry. If you're building out a Black Sageo Ninjato display collection, this piece anchors the theme with its all-black hardware and silver accent fittings.

At 41 inches in length and 4 lbs, this is a full-size replica suited to wall mounting, shelf display, or cosplay use. Sword stand not included. Packaged in a 43 x 4 x 4 inch box with a shipping weight of 5 lbs. Because each sword is handmade individually, minor dimensional and finish differences are expected and are part of the character of the piece.
