T10 Carbon Steel Tachi Sword with Hamon Blade, Red Lacquer Saya and Gold Peony Tsuba

The blade of this tachi is forged from T10 carbon steel, ground to a 28.74 in nagasa and heat-treated to 62 HRC. A natural hamon line runs along the edge, produced through the differential hardening process - the wavy transition between hard edge and softer spine is visible in direct light and gives each blade a unique character. The hand-finished surface carries a chrome-polished clarity that highlights the geometry of the shinogi and the curvature of the sori.

The tsuka measures 10.62 in and is built on a full tang construction. Black real rayskin (samegawa) wraps the wooden core, and brown cotton ito is wound over it in the traditional diamond-gap pattern, locking the wrap securely and exposing the rayskin nodes at each crossing. The combination delivers both grip texture and visual contrast against the gold fittings above and below.

The tsuba is cast from alloy in a gold tone and shaped to an ornate irregular silhouette filled with peony relief carving. Scrolling leaves and layered petals cover the surface, making it one of the most visually complex elements of the koshirae. Matching gold-tone fuchi and kashira complete the handle assembly, tying the metalwork together into a unified decorative set.

The saya is shaped from hardwood and finished in a matte red lacquer. Black dragon-motif inlays run along the body of the scabbard, creating a striking contrast against the red ground. Gold-tone alloy fittings at the koiguchi and kojiri echo the tsuba's metalwork. A red-white-black braided sageo cord is attached at the kurikata and tied in a traditional looped knot, completing the koshirae presentation. At 29.92 in, the saya fits the blade with a clean, secure draw.

Overall length is 40.55 in with a total weight of 2.8 lb. The piece is finished in a full koshirae style - blade, handle, guard, and scabbard coordinated as a matched set - suited for horizontal wall mounting or display stand presentation.
