Black Blade Katana in Manganese Steel with Kanji Engraved Saya and Red-Black Tsuka Wrap

The blade of this katana is forged from high manganese steel and finished in a deep black coating that runs from habaki to kissaki, with a clearly defined hamon line tracing the edge. The steel offers solid toughness and retains a hand-finished edge throughout its 41-inch overall length. At 3 lb, the sword carries real presence in hand, and the full-tang construction ensures the blade seats firmly through the entire handle assembly without flex or movement. Collectors drawn to the Black Blade Samurai Sword category will recognize the dramatic contrast this treatment creates against the bright hamon.

The tsuka is built on a hardwood core and wrapped in black cord over red PU samegawa in a classic hishi-gumi diamond pattern. The alternating red diamonds visible through the black wrap create a layered, high-contrast look that holds securely under extended handling. The wrap terminates cleanly at both kashira and habaki, with no loose ends or gaps in the pattern.

The tsuba is iron-finished in matte black with a circular cutout scroll motif visible on the face. The fuchi collar transitions from tsuba to tsuka with a gold-tone habaki band that provides a warm metallic accent between the black handle and black blade. This detail anchors the sword's red-black-gold palette at the crossguard junction.

The saya is shaped from hardwood and finished in a high-gloss piano-black lacquer that reflects cleanly in light. Two decorative elements are applied to the saya's face: a detailed samurai armor scene rendered in silver-white near the koiguchi, and bold gold kanji script above it. The red sageo is knotted at the kurikata in a wrapped bundle finish, adding the final color accent that echoes the tsuka's red samegawa. Those seeking similar lacquer quality can explore the Handwood Scabbard Katana collection for related pieces.

This koshirae-mounted katana ships in a reinforced 43 x 4 x 4-inch box at 4 lb shipping weight. The sword stand is not included. The combination of black steel, piano-lacquer saya, kanji artwork, and red cord accents makes this piece a focused collector's item for anyone building a Japanese sword display around a bold monochromatic aesthetic.
