1090 Carbon Steel Katana with Blue Blade, Black Hardwood Saya and Lion Tsuba

The blade is forged from 1090 carbon steel and finished in a deep, even blue tone that runs the full length of the nagasa. Without a traditional hamon, the surface reads as a clean gradient from spine to edge - a deliberate aesthetic choice that gives this piece its modern visual identity while retaining the classic single-edge geometry of a Japanese katana. At 40.55 inches overall with a blade width of 1.259 inches, the proportions follow standard katana form. If you're exploring the broader range of Blue Steel Sword options, this piece sits squarely in that visual tradition.;

The tsuka is built over a full-tang core and wrapped first in PU black samegawa for grip texture, then finished with tightly wound black cord ito. Gold-tone menuki are set beneath the ito wrapping, visible as small decorative anchors along the handle - a detail that lifts the mounting beyond purely utilitarian construction. The black-and-white braided sageo is knotted at the kurigata in a compact traditional style, adding visual contrast at the transition point between saya and tsuka.

The tsuba is cast alloy in a lion relief design - black overall with a gold-tone oval seppa at center. The lion motif is rendered with enough sculptural detail that the individual forms read clearly: flowing mane, defined facial features, and layered texture across the surface. It's an assertive design that anchors the koshirae and creates a strong midpoint between the blue blade and the black saya.

The saya is hardwood finished in a high-gloss black lacquer. The deep gloss finish creates a deliberate contrast with the matte blue of the blade when drawn, and the fit between blade and saya is clean. The overall package - black saya, black-and-white sageo, gold-accent fittings, and blue nagasa - forms a cohesive color story that photographs well and displays cleanly on a wall mount or stand.

At 2.8 lb and 40.55 inches, this katana is a substantial piece suited for collectors, cosplay use, or decorative display. The full koshirae assembly is complete as shown; sword stand is not included. For related options in this visual style, see the Blue Katana collection.
