T10 Carbon Steel Katana with Red Rayskin Saya - Full Tang, Real Hamon, Black Scroll Tsuba

The blade is forged from T10 carbon steel and hand-finished to a hardness of 62 HRC, producing a genuine hamon temper line along the full 28.74-inch nagasa. The chrome-polished surface brings out the contrast between the hardened edge and the body of the steel, making the hamon visible from almost any angle. At 1.259 inches wide, the geometry is consistent with traditional katana proportions and supports the full-tang construction that runs through the entire handle.

The tsuka measures 10.62 inches and is wrapped in red ito cord over a base of authentic black rayskin samegawa. Knot-paper wrap technology is applied beneath each crossing of the cord to keep the diamonds tight and even over time. The result is a handle that holds its pattern and provides a reliable grip without relying on adhesive alone.

The tsuba is cast from alloy in a rounded form and finished in matte black. Hand-carved ornate scroll detailing covers the face of the guard, giving it visual weight that matches the boldness of the red-and-black color scheme. The gold-tone habaki collar seats cleanly against the tsuba face and transitions the blade into the handle assembly without play or rattle.

The saya is wrapped in genuine red rayskin with a matte surface texture across its 29.92-inch length. Real-horn koiguchi and kojiri fittings are fitted at the mouth and tip - materials that are denser and more dimensionally stable than synthetic alternatives. A black sageo cord is knotted at the kurikata, completing the Multi-colored Saya Katana aesthetic with a clean contrast against the red body.

Overall length is 40.55 inches and the sword weighs 2.8 lb. The koshirae-style mounting brings together every fitting - blade, handle, tsuba, and saya - in a unified red-and-black presentation. For collectors drawn to the traditional samurai color palette, this piece sits naturally alongside Red Hardwood Japanese Samurai Swords and similar historically influenced designs.
