T10 Carbon Steel Clay Tempered Katana with Real Hamon in Red Lacquered Saya and Copper Floral Tsuba

The blade of this katana is forged from T10 carbon steel and clay tempered to produce a genuine hamon line visible along its 28.74-inch cutting edge. This differential hardening process creates a harder edge backed by a more resilient spine, and the resulting hamon pattern is unique to each piece. The steel achieves a hardness of 58 HRC, and the surface is hand polished to a high mirror finish that highlights the grain structure and temper line.;

The handle measures 10.23 inches and is built on a full tang core secured through the hardwood grip. Red PU samegawa wraps the handle beneath a tightly wound black cotton cord in a traditional crosshatch pattern. Red diamond-shaped accents peek through the black ito at regular intervals, echoing the saya's color and adding visual rhythm to the tsuka.

Protecting the hand is a round copper tsuba decorated with a chrysanthemum and leaf motif. One side features gold-gilded blossoms while the other displays silver-toned foliage, creating an asymmetric design that rewards close inspection. The copper base carries a warm, aged patina that contrasts with the metallic gilding. This style pairs well with other pieces in our Red Katana collection.

The saya is crafted from hardwood and coated in a deep red piano lacquer that produces a glossy, translucent finish. Black etched patterns depicting traditional motifs adorn the upper section of the scabbard, and a black braided sageo cord is tied at the kurikata with a neat knot. The red lacquer catches light with a rich, almost marbled depth that complements the copper and gold tones of the fittings.

At 41 inches overall and 4.4 lbs, this katana carries genuine presence as a display piece. The coordinated red-and-black color scheme runs from saya to tsuka, unified by gold and silver accents on the tsuba and menuki. For collectors drawn to bold color combinations, our T10 Carbon Steel Katana collection offers additional options in this style range.
