T10 Carbon Steel Black Katana with Clay Tempered Hamon in Piano Lacquer Saya - Full Tang Collectible Sword

The blade of this black katana is forged from T10 carbon steel and subjected to a clay tempering process that creates a genuine hamon along the edge line. With a hardness of 60 HRC, the 28.3-inch nagasa holds its refined edge while the softer spine absorbs shock. The chrome-polished steel surface contrasts beautifully against the dark fittings, and the kissaki tip is ground to a clean, precise geometry visible in every angle. This is a standout piece among Clay Tempered Samurai Swords for collectors who value authentic heat treatment.

The 10.2-inch tsuka is built on a hardwood core covered in real white samegawa - genuine ray skin that adds both grip texture and traditional authenticity. Over the samegawa, black cotton cord is tightly wrapped in a diamond pattern, secured at each menuki point. The contrast between the white ray skin peeking through the black wrapping gives the handle a classic katana appearance.

A round alloy tsuba in black sits between the handle and blade, simple in profile but effective in proportion. Just above the tsuba, the habaki collar displays a warm copper tone with subtle ridged detailing that catches light and provides a visual bridge between the dark fittings and the bright steel.

The 30.3-inch hardwood saya is finished in a deep piano lacquer that produces a mirror-like black surface. Near the koiguchi (scabbard mouth), a section of pearl rayskin wrapping adds a textured accent that breaks up the gloss. The black sageo cord is neatly tied around the kurikata, and real horn fittings at the koiguchi reinforce the opening for repeated draw and sheathe.

At 40.5 inches overall and 2.65 lbs, this full tang T10 Katana Sword balances well in hand. Every component - from the clay tempered blade to the lacquered saya - follows a cohesive all-black theme accented only by the copper habaki and white samegawa. It is designed for the collector who appreciates understated Japanese aesthetics backed by genuine steel craftsmanship.
