T10 Carbon Steel Katana with Clay-Tempered Blade, Gold-Black Tsuba in Black-White Koshirae

The blade on this katana is forged from T10 carbon steel and clay-tempered, producing a real hamon line that traces the boundary between the hardened edge and the softer spine. The black-finished nagasa carries hand-engraved text along its face, and the polished edge contrasts cleanly against the matte body. At 41 inches overall with a 1.259-inch width at the widest point, the blade geometry follows a traditional shinogi-zukuri profile suited for display in any serious collection. For collectors drawn to Full Tang Katana Sword builds, the steel runs uninterrupted through the tsuka for solid one-piece integrity.

The tsuka is wrapped in black-and-white diamond-pattern ito over real white samegawa - the ray skin visible through the gaps creates a high-contrast texture that holds its shape over time. The black cotton wrap has a firm, non-slip grip character, and the overall handle construction keeps the 3 lb weight balanced toward the center of the assembly.

The tsuba is cast in a gold-black finish with an ornate scroll theme - raised swirl and cloud motifs fill the face of the guard, and the brass-tone frame reads as a deliberate accent against the black handle and saya. The fuchi and kashira fittings carry matching metalwork, tying the koshirae together without visual breaks.

The saya is built from hardwood and finished in a deep black lacquer coat. The surface is smooth and even, with a clean fit at the koiguchi. A black-and-white braided sageo cord is knotted at the kurikata, echoing the tsuka-ito pattern and completing the monochrome-plus-gold color scheme across the full assembly. Collectors exploring other finishes in this steel grade will find related options in the Blue Blade T10 Carbon Steel Katana collection.
