T10 Carbon Steel Katana with Blue Lacquer Saya - Gold Geometric Tsuba, Black Ito

The blade on this katana is forged from T10 carbon steel, a high-carbon steel known for its edge retention and visible differential hardening results. A real hamon line runs along the edge, produced through the heat treatment process and visible as a distinct contrast between the hardened edge and the body of the blade. At 40.5 inches overall with a 1.26-inch width, the full tang construction anchors the blade securely through the handle with a chrome-polished finish that reflects cleanly in the light.

The tsuka is wrapped in black cotton ito over genuine white samegawa ray skin, the classic diamond-pattern binding exposing the bright samegawa at each crossover point. The contrast between the black cord and white ray skin gives the handle a clean, high-contrast look that reads well against the overall color scheme. Warm brown fuchi and kashira collar fittings frame the handle at both ends.

The gold-tone tsuba features an open geometric lattice pattern - rectangular cutwork set in a square frame with a textured border. This style of tsuba draws from traditional Japanese metalwork and sits as a deliberate visual anchor between the polished blade and the dark handle. The warm gold tone bridges the brown fittings and the blue saya without competing for attention.

The saya is lacquered hardwood finished in deep blue with a fine gold-flecked surface texture visible in direct light. A braided blue-black sageo cord is secured at the kurikata and hangs in a traditional knotted arrangement, the tassel ends finished with blue thread. The color pairing of the blue saya against the black-wrapped handle and gold tsuba gives this piece a cohesive, refined presentation.
