1065 Carbon Steel Full Tang Katana with Sky Blue Marble Saya and Silver-Gold Floral Tsuba

The 28.74-inch blade is forged from 1065 carbon steel and hand-finished to a bright chrome polish. A real hamon line runs along the edge, created during the hardening process and visible as a subtle grain shift near the cutting surface. Hardened to 62 HRC, the full tang construction extends through the handle for structural integrity. Japanese characters are engraved near the habaki, adding a traditional signature detail to the steel.

The 10.62-inch tsuka is built on a foundation of black real rayskin, tightly wrapped in sky blue cotton cord using a traditional diamond-pattern ito. Gold menuki ornaments sit beneath the wrap on each side, providing subtle grip landmarks. The pairing of blue cord against the black samegawa creates a clean contrast visible through the wrap openings, consistent with the overall color theme of this piece.

A round alloy tsuba serves as the guard, featuring an openwork silver design of curving stems and botanical forms. One section is finished in gold leaf, creating a two-tone effect that catches light at different angles. The silver habaki collar and matching fuchi-kashira fittings complete the hardware, tying the metalwork together in a unified silver and gold palette.

The 29.92-inch hardwood saya is the visual centerpiece of this katana. Its surface carries a vivid sky blue base with a web of fine red and pink marble veining sealed under natural lacquer - a pattern that resembles cracked ice or abstract branch work. A blue braided sageo cord wraps the kurikata, and the kojiri endcap matches the blue theme. This saya design pairs naturally with other pieces in the Full Tang Carbon Steel Katana collection.

At 40.55 inches overall and 2.8 lbs, this 1065 carbon steel katana balances visual detail with traditional proportions. The coordinated blue-and-silver color scheme, floral tsuba, and marble-finish saya make it a distinctive addition to any Japanese sword collection or wall display.
