T10 Carbon Steel Katana with Snake Tsuba - Dark Red Saya & Teal Sageo, Full Tang

The blade on this katana is forged from T10 high-carbon steel and hand-finished to produce a visible hamon line tracing the edge - the natural result of differential heat treatment that gives each sword its own distinct temper pattern. The chrome-polished surface reflects cleanly under light, with the wavy hamon boundary running the full length of the cutting edge as seen in the close-up product imagery.

The tsuka is wrapped in black cotton cord over white same (ray skin), bound in a traditional diamond-lozenge pattern. White menuki ornaments are set beneath the wrap at regular intervals, visible through the diamond gaps. The handle wrapping uses 10mm cord for a firm, non-slip grip surface with consistent tension throughout the binding.

At the blade collar, a black-and-gold snake tsuba commands immediate attention. The cast iron guard features a coiled serpent rendered in raised relief with gold-tone detailing along the scales and head - a bold thematic choice that anchors the koshirae aesthetic. Brass habaki and fuchi fittings seat the blade securely and provide the warm metallic transition between guard and handle.

The dark red hardwood lacquer saya is the visual counterpoint to the black handle - a deep burgundy finish that photographs as near-maroon under direct light. A teal sageo cord is tied at the kurigata in a traditional knot, adding a third color to the palette and echoing the green tones visible on the tsuba patina.

Overall length is 41 inches with a shipping weight of 4 lbs, packaged in a 43 x 4 x 4 inch box. Each piece is individually handmade, so minor variation in hamon pattern and fitting tone is inherent to the process. Sword stand not included. For collectors drawn to serpent iconography and bold color contrasts, this full-tang koshirae katana is a coherent, well-executed ensemble from tip to saya.
