T10 Carbon Steel Clay Tempered Katana with Real Hamon - Red Rayskin Saya and Copper Dragon Tsuba

This full tang katana features a T10 carbon steel blade that has been clay tempered to produce a distinctive real hamon temper line running along its length. The clay tempering process creates differential hardness - a harder edge paired with a more resilient spine - while leaving a visible, organic wave pattern unique to each individual piece. The blade carries a dark, polished finish that makes the hamon line stand out with striking clarity.

The tsuka is built on a hardwood core wrapped first in genuine red samegawa (ray skin), then bound tightly with black cotton ito cord in a traditional crisscross pattern. The red samegawa peeks through the diamond-shaped gaps in the wrapping, creating a bold red-and-black contrast that defines the handle's character. This layered construction provides both visual depth and a firm, textured grip.

At the guard position sits a copper tsuba featuring a sculpted dragon motif with gold gilding accents. The dragon design is rendered in high relief with fine detail in the scales and flowing mane, making the tsuba a focal point of the sword's fittings. This piece pairs well with other selections from our T10 Steel Katana collection for those building a curated display.

The saya is crafted from hardwood finished in premium natural lacquer, with the upper section wrapped in red pearl rayskin that matches the samegawa on the handle. A black sageo cord is tied around the kurikata in a traditional knot, adding both function and a clean finishing detail. The glossy red rayskin against the lacquered black body gives the scabbard a layered, textured appearance.

Measuring 41 inches in overall length and weighing 3 lbs, this katana is sized for display presence without excess bulk. The cohesive red, black, and gold color palette - from handle to saya to fittings - makes it a strong centerpiece among Full Tang Japanese Katana Sword collections or as a standalone display piece on a traditional katana stand.
