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 Carbon Steel Katana 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 Wave Theme Blade Katana collection.
