T10 Carbon Steel Katana with Real Hamon - Dark Red Lacquer Saya & Beige Cord Handle

The 28.74-inch blade is ground from T10 carbon steel and hardened to 62 HRC, producing a hand-finished edge with a visible real hamon line that traces the full length of the chrome-polished nagasa. The hamon's natural wave pattern is a direct result of the differential heat treatment process, giving the blade a two-tone surface character that sets it apart from standard mono-steel finishes. At 1.259 inches wide and 0.275 inches thick at the spine, the geometry balances presence with clean taper toward the kissaki.

The tsuka measures 10.62 inches and is built over a genuine black rayskin (samegawa) foundation - a traditional material prized for its grip texture and durability. Beige cotton ito is wrapped in a classic diamond-pattern braid over the samegawa, creating the visual contrast and tactile control associated with koshirae-style construction. The overall handle feel reflects the proportions of a full tang build spanning the complete length of the grip.

The tsuba is a round alloy piece finished in gold tone, cast with an ornate scroll relief across its face. Embossed dots and a central medallion design cover the surface, referencing classical Japanese decorative motifs. A matching menuki accent visible beneath the ito cord ties the fittings together in a cohesive gold-and-beige palette.

The saya is shaped from hardwood and finished in a matte dark red lacquer with black mottled patterning across the surface - a visually striking effect that reads as aged or stone-textured under direct light. At 29.92 inches, it fully houses the blade with a snug koiguchi fit. A beige sageo cord is knotted at the mouth of the saya in a traditional multi-loop braid, adding functional elegance and completing the red-and-beige color story carried through every component. The Red Samurai Armor collection pairs naturally with this saya's deep crimson finish for display groupings.

Total assembled length is 40.55 inches with a weight of 2.8 lbs. Shipping weight is 3.3 lbs in a 42.9 x 3.9 x 3.5-inch package. The koshirae-style fittings - beige ito, gold tsuba, dark red lacquer saya, and real hamon blade - form a coherent traditional presentation suited for collectors, display cases, or kata practitioners who value authentic component construction.
