T10 Folded Steel Clay Tempered Katana with Real Hamon in Black Saya and Red-Black Cord Wrap

This katana features a T10 carbon steel blade that has been folded and clay tempered to produce a genuine hamon - the wavy temper line visible along the edge where differential hardening creates a natural contrast between the hardened cutting edge and the softer spine. The blade reaches 28.74 inches, carries a hardness of 58 HRC, and displays a clean chrome-toned finish that highlights the hamon pattern in direct light. As part of the Clay Tempered Katana Sword collection, this piece showcases the depth of traditional Japanese heat-treatment technique.

The tsuka measures 10.23 inches and is built on a full tang construction with a hardwood core. PU red samegawa provides texture and visual warmth beneath a tightly wound black cord ito wrap. Small gold-toned menuki sit beneath the wrapping, and the combination of red underlayer with black cord gives the handle a distinctive red-black accent pattern.

At the junction of blade and handle sits a round iron tsuba with gold-toned accents and intricate hollow cutout patterns. The openwork design creates a layered silhouette effect, and a copper habaki collar seats the blade firmly into the guard assembly. The craftsmanship here balances structural integrity with visual detail.

The saya is carved from hardwood and finished in piano lacquer with a baking varnish topcoat that produces a frosted, subtly textured black surface. At 30.7 inches, it houses the blade securely, and the black and red braided sageo cord is tied at the kurikata in a traditional knot. The frosted finish catches light differently than a high-gloss saya, giving this piece a muted, understated character.

Overall, the katana measures 41 inches in length and weighs 4.4 lbs. From the folded T10 steel blade to the frosted hardwood saya, every component reflects careful hand assembly. Whether displayed alongside other Red-black Katana pieces or presented as a standalone collectible, this sword delivers substance in both material and visual design.
