Product Details

The blade on this katana is forged from T10 carbon steel and clay-tempered to develop a natural hamon line that runs the length of the black-finished nagasa. The hardening process creates a visible contrast between the hardened edge and the body of the blade, a defining characteristic of traditional Japanese sword craft. At 40.5 inches overall with a 1.26-inch width at the base, the geometry is well-proportioned for a standard katana silhouette.

The tsuka is built over a full tang foundation, meaning the steel core extends completely through the handle for structural integrity and balanced weight distribution. Black PU samegawa wraps the wooden core beneath tightly wound black cord ito, with small menuki hardware visible at intervals along the wrap. The result is a handle that reads as cohesive and traditionally proportioned.

The tsuba is the most visually complex element of this koshirae. Cast in black alloy, it features deeply carved dragon imagery across its surface, with a gold chrysanthemum medallion inlaid at the center opening. The black-and-gold contrast makes this guard a genuine focal point against the all-black handle and blade assembly.

The saya is constructed from hardwood with a black lacquer finish, producing a smooth, gloss surface that mirrors the blade's dark tone. A black sageo cord is knotted through the kurigata, finished in a traditional braided style at the opening. The overall koshirae maintains strict all-black color discipline from tip to kashira. For collectors seeking similar sword configurations, the Authentic Japanese Sword collection offers additional curated options.

This katana weighs 3.17 lbs and ships in packaging measuring 43.3 x 3.93 x 3.14 inches. The sword stand is not included. Intended as a collectible display piece representing traditional Japanese sword aesthetics in a unified black-and-gold color scheme.
