Product Details

The blade on this katana is forged from T10 carbon steel and clay tempered using a traditional water-quench process, producing a genuine hamon line that runs the length of the 28.3-inch nagasa. At 60 HRC, the steel holds a hand-finished edge while retaining the flex needed for a full-tang piece of this length. If you're building a collection around high-carbon construction, this sits comfortably within our T10 Katana lineup.

The tsuka is 10.2 inches long, wrapped in black ito over what appears from the image to be a teal rayskin (same) base. The tight diamond-pattern wrap reveals the rayskin through each gap, and the black menuki hardware punctuates the grip at the traditional positions. The overall handle color reads as a strong teal-black contrast against the polished blade.

The tsuba is one of the most visually detailed elements of this piece. Cast in alloy, it carries a raised floral motif - blossoms and leaves rendered in silver and gold tones against a darkened ground. The rectangular habaki slot is framed with a gold-tone border, and the surrounding floral work gives the fitting an almost sculptural quality that rewards close inspection.

The saya is cut from hardwood and finished in a deep gloss piano lacquer that gives the black surface a near-mirror reflection. The koiguchi section is wrapped in the same teal rayskin as the handle, tying the two components together visually. Black sageo cord is knotted and draped at the kurikata in the standard koshirae style. For similar scabbard treatments, see our Green Scabbard Japanese Samurai Swords collection.

Overall length is 40.5 inches with a blade width of 1.26 inches and a total weight of 2.65 lbs. The piece ships in a fitted box measuring 43.4 x 3.9 x 3.14 inches at a shipping weight of 3.4 lbs - proportionate packaging for a full-length katana of this spec.

Frequently Asked Questions

What steel and hardness does this katana blade use?
The blade is forged from T10 carbon steel and clay tempered with a water-quench process, reaching 60 HRC. This produces a visible hamon line along the 28.3-inch nagasa and a hand-finished edge on the full-tang construction.
What does the floral tsuba look like up close?
The alloy tsuba features raised blossoms and leaves in silver and gold tones on a darkened ground, with a gold-bordered habaki slot at center. The relief detail is substantial enough to be a focal point of the koshirae presentation.
How does the teal rayskin tie into the saya finish?
The teal rayskin wraps both the tsuka base and the saya's koiguchi section, creating a matched accent against the black cord wrap and deep gloss piano-lacquer scabbard. The black sageo cord completes the two-tone color scheme.
