Product Details

The blade on this katana is forged from T10 carbon steel and hand-finished to carry a genuine hamon - the wavy temper line that runs along the edge is produced through the heat-treatment process itself, not added by etching afterward. At 40.5 inches overall with a 1.26-inch width at the base and a spine thickness of 0.28 inches, the geometry follows traditional Japanese sword proportions. The chrome-polished surface lets the hamon stand out cleanly against the steel.

The tsuka is built on a full-tang foundation, meaning the steel extends uninterrupted from kissaki to kashira. Black cotton ito is wrapped over white PU samegawa (ray-skin), creating the familiar diamond-window pattern. Brown sageo cord ties at the saya opening, adding a contrasting earth tone to the otherwise dark handle assembly.

The bronze tsuba is cast in a wave theme, with carved cloud-and-wave scrollwork filling the disc and negative-space cutouts that give it an open, layered look. Bronze fuchi and kashira fittings carry the same warm metallic tone through the rest of the koshirae hardware, keeping the overall palette cohesive.

The hardwood saya is lacquered in deep black with a red vine-and-marble pattern running the full length - no two scabbards come out identical, so the exact distribution of red veining varies piece to piece. A brown sageo cord wraps the koiguchi end in a layered knot, reinforcing the connection point and adding a final decorative element. If you're building a Natural-wood T10 Carbon Steel Katana collection, the hardwood saya on this piece fits comfortably within that aesthetic.

Overall length is 40.5 inches, width 1.26 inches, spine 0.28 inches, and the sword weighs 3.2 lb. Each piece is individually handcrafted, so minor variation in hamon shape and lacquer pattern is inherent to the process. Sword stand not included.

  • Blade forged from T10 carbon steel with a visible real hamon along the edge - the natural temper line is a direct result of the heat-treatment process, not an etched imitation.
  • Full-tang construction runs the steel continuously from tip through tsuka, providing solid structural integrity across the 40.5-inch overall length and 3.2 lb balanced weight.
  • Black hardwood saya finished in a deep lacquer with red vine-pattern marbling - the dramatic two-tone surface gives each scabbard a distinct, hand-applied character.
  • Bronze wave-theme tsuba cast with swirling cloud-and-wave relief, paired with matching bronze fittings that unify the koshirae hardware in a warm antique tone.
  • Black cotton ito wraps the tsuka over a white PU ray-skin base, forming a classic diamond pattern - brown sageo cord ties at the saya for a traditional presentation.

What does the tsuba look like and what is the saya finish?
