Clay Tempered T10 Steel Katana with Hamon Line in Red Piano Lacquer Saya - Black and Red Sageo

The blade is forged from T10 carbon steel using a clay tempering process that produces a natural hamon line along the edge. At 28.74 inches, the full tang nagasa is hand-finished and hardened to 58 HRC, delivering both visual character and lasting durability. The chrome-toned steel surface highlights the undulating temper line from spine to edge, a signature mark of traditional differential hardening.

The tsuka measures 10.23 inches and is wrapped in black cotton cord over genuine white rayskin samegawa. The alternating diamond pattern of the ito wrap provides texture and grip, while the rayskin beneath adds a layer of structural support. Gold-toned menuki accent pieces sit beneath the wrap, visible through the cord gaps.

At the guard position, a black alloy tsuba features an openwork design with a floral motif. The cutout pattern allows light to pass through, creating depth and visual interest. A brass-finished habaki seats the blade firmly into the tsuba assembly, and a matching fuchi-kashira set in black frames both ends of the handle.

The saya is crafted from hardwood and finished in a high-gloss red piano lacquer that gives it a deep, reflective surface. Braided sageo cord in black and red wraps around the kurikata knot, complementing the overall color palette. The saya measures 30.7 inches and fits the blade snugly with a satisfying click. This piece pairs well with other swords from the Red T10 Carbon Steel Katana collection.

With an overall length of 40.94 inches and a weight of 4.4 lbs, this katana carries real presence as a display piece. Every component - from the clay tempered blade to the lacquered saya - reflects deliberate material choices and traditional construction. For collectors drawn to Clay Tempered Samurai Sword craftsmanship, this red and black combination delivers on both form and detail. Sword stand not included.
