T10 Carbon Steel Katana with Clay Tempered Real Hamon in Hand-Painted Beige Saya with Copper Fittings

This katana features a T10 carbon steel blade that has been clay tempered to produce a distinctive real hamon line running along the 28.74-inch cutting edge. The differential hardening process yields a hardness of 58 HRC at the edge while maintaining flexibility in the spine, and the polished chrome-tone finish reveals the natural grain pattern created during forging.

The 10.23-inch tsuka is constructed over a hardwood core wrapped in black PU samegawa, then bound tightly with dark brown cotton ito cord in a traditional crosshatch pattern. The full tang extends through the entire handle and is secured with a mekugi pin, providing solid structural integrity throughout the assembly.

A real copper tsuba serves as the centerpiece of the fittings, featuring a deeply carved samurai-theme relief with an antique brass patina that matches the copper fuchi and kashira end caps. The level of sculptural detail in the tsuba elevates this piece among Hamon Japanese Sword collectibles that prioritize authentic metalwork.

The hardwood saya is finished with premium natural lacquer in a warm beige tone and showcases a hand-painted illustration of a female figure rendered in rich sepia and brown tones. A dark brown sageo cord is tied around the kurikata in a decorative knot, complementing the saya artwork and the overall dark brown color palette of the handle and fittings.

At 40.5 inches in overall length and 2.9 lbs, this Full Tang Carbon Steel Sword balances display presence with authentic proportions. The combination of clay tempered T10 steel, hand-painted saya artwork, and copper fittings positions this katana as a distinctive collector's piece that merges traditional forging methods with artistic saya craftsmanship.
