Full Tang Katana in High Manganese Steel with Marble Saya and Black-Red Tsuka

The blade on this katana is forged from high manganese steel and finished with a bright chrome polish that highlights the clean lines of its single-edged geometry. The precision-finished edge runs the full length of the nagasa, and the full tang construction ensures the steel extends continuously into the handle for solid, integrated structure. For collectors interested in High Manganese Steel katana options, this piece represents the material's characteristic brightness and durability.

The tsuka is built over a hardwood core and wrapped in black ito cord with a classic diamond-pattern wind, exposing the red PU samegawa beneath at each opening. The contrast between the black cord and the red underlayer creates a vivid, graphic look along the full length of the handle. Alloy fittings at the fuchi and kashira complete the handle assembly in matching black tones.

The tsuba is a black alloy piece with an open geometric cutout design - a circular frame intersected by angular negative space - giving it a bold, structural appearance without ornate embellishment. It sits flush between blade and handle and coordinates cleanly with the black metalwork throughout the koshirae.

The saya is the most visually distinctive element of this build. Constructed from hardwood with a lacquer finish, it carries a marble-effect surface pattern in black and white with scattered red detail across the full length of the scabbard. The black-and-red sageo cord wraps the kurigata in matching tones, tying the saya visually back to the tsuka. This kind of expressive saya finish is a hallmark of contemporary koshirae-style builds found across the Real Japanese Katana Sword collection.

Overall length is 41 inches and the piece weighs 4 pounds. Shipping weight is 5 pounds in a 43 x 4 x 4-inch package. Note: sword stand or holder is not included.
