T10 Carbon Steel Katana with Blue Lacquer Saya, Floral Black-White Tsuba, Brown Ito

The blade on this katana is forged from T10 carbon steel and finished with a hand-polished hamon that traces the full length of the nagasa. The hamon line is clearly visible - a bright, wavy boundary between the hardened edge and the softer spine - giving the chrome-finished blade both visual depth and structural definition. At 40.55 inches overall with a blade width of 1.259 inches, the geometry follows classic katana proportions.

The tsuka is wrapped in brown ito over a foundation of genuine white samegawa, with the diamond-pattern binding pulled tight to expose evenly spaced menuki beneath. The brown-over-white layering creates warm contrast against the cooler tones of the blade and saya, and the wrap stays firm across the full handle length.

The tsuba is one of the most distinctive elements of this piece. Cast in black copper, it carries a detailed floral engraving rendered in white relief - peony-like blooms and scrolling foliage fill the surface in a style consistent with classical Japanese sword fittings. A polished silver habaki seats cleanly between tsuba and blade, completing the transition from fittings to steel. Explore the full range in our Blue T10 Carbon Steel Katana collection.

The saya is shaped from hardwood and finished in deep blue lacquer with a high-gloss surface. Gold fleck detailing runs along the body of the scabbard, catching light at different angles. The blue-and-white braided sageo is knotted at the koiguchi and hangs with enough length for traditional-style securing or decorative draping - the real horn koiguchi and kojiri fittings reinforce the saya at both ends.

At 2.8 lbs and packaged at 42.9 x 3.9 x 3.5 inches, this koshirae-style katana is built for display and collection. The combination of blue lacquer saya, brown ito, black-white floral tsuba, and chrome blade makes it a visually cohesive piece that holds its own among Cool Samurai Swords built to the same standard of craftsmanship.
