Product Details

The blade on this katana is forged from 1090 carbon steel and finished in a deep dark blue with scattered gold dragon engravings across the flat, giving it the appearance of a storm-worn sky. The nagasa measures 40.5 inches in total sword length, with a blade width of 1.26 inches and a spine thickness of 0.275 inches. If you appreciate blades with bold visual character, this one fits naturally alongside other pieces in the Marble Japanese Samurai Swords family - similarly dramatic surface treatments on 1090 steel.

The tsuka is built on a full tang core, ensuring the handle and blade move as a single unit. Black PU samegawa forms the base layer beneath a tight black cord wrap finished in a traditional diamond pattern. Silver menuki accents are set into the wrap at the standard positions, visible through the binding and adding a fine detail that rewards close inspection.

The tsuba is one of the most detailed elements of this build. Cast in alloy with a silver base and gold accent plating, the openwork design features a coiled dragon in relief against a pierced background - a motif that carries through to the blade engravings and ties the entire koshirae together visually. The fuchi collar continues the silver-gold pairing established by the tsuba.

The saya is constructed from hardwood with a matte black lacquer finish, shaped to a clean oval cross-section with no surface ornamentation - letting the blade's blue and gold tones lead when the sword is drawn. A black sageo cord is knotted at the kurikata, and the kurikata itself is finished in matching black with a sculpted form. For collectors exploring the full range of 1090 Katana options, this piece offers one of the more visually distinctive blade treatments in that steel category.

Overall weight is 3.17 lbs. Packaged dimensions are 43.3 x 3.93 x 3.14 inches with a shipping weight of 4.4 lbs. Sword stand not included.

Frequently Asked Questions

What steel is used and how hard is the blade?
The blade is made from 1090 high-carbon steel, a proven medium-to-high carbon alloy known for toughness and edge retention. The dark blue finish is a surface treatment applied over the polished steel, not a coating that affects hardness.
What do the gold markings on the blue blade represent?
The gold markings are dragon engravings hand-applied along the nagasa, echoing the dragon motif on the tsuba. The combination of deep blue steel and gold dragon imagery ties the blade and fittings into a unified koshirae-style visual theme.
How is the tsuba designed and what is the saya made of?
The tsuba is cast alloy with silver base plating and gold accent details, featuring a pierced openwork dragon in relief. The saya is constructed from hardwood with a matte black lacquer finish, paired with a black sageo cord and sculpted black kurikata.
