1095 Carbon Steel Katana with Dark Red Blade, Black-Red Tsuka & Marble Saya - Full Tang Replica

The blade of this katana is forged from 1095 carbon steel with manganese added for toughness, heat-treated to 62 HRC and ground to a hand-finished edge. A visible hamon line runs along the 28.74-inch nagasa, the result of differential hardening that leaves a distinct temper pattern between the edge and spine. The dark red coloring across the blade face sets this piece apart from standard polished finishes, giving it a striking visual signature that reads clearly even at a distance. Collectors drawn to Colored Blade Katana will find the tone consistent and even along the full length.

The full-tang construction extends through the 10.62-inch tsuka, giving the assembly a single continuous steel core. The handle is wrapped in genuine black rayskin (samegawa) beneath black ito cord, with red diamond-shaped gaps spaced evenly along the wrap. The combination holds securely without adhesive dependence and provides a textured grip surface that resists slipping during extended handling.

The tsuba is cast alloy in a round open-work format with an ornate scroll cutout pattern. Black with gold accent details on the seppa, it creates a clean visual break between the handle and blade. The relief work on the surface adds depth to the fitting without adding bulk, and the sizing is proportional to both the tsuka length and blade width.

The saya is hardwood lacquered in a matte black marble finish - a dark base scattered with fine light speckles that give the sheath a textured, stone-like appearance. At 29.92 inches, it accommodates the full nagasa with a snug fit at the koiguchi. A red-and-white striped sageo is tied at the kurikata in a layered decorative knot, adding the primary color accent to the otherwise dark koshirae. This Granite 1095 Carbon Steel Katana collection shares a similar aesthetic approach to patterned saya finishes.

Overall length is 40.55 inches with a total weight of 2.8 lbs. The koshirae-style fittings and consistent color pairing across sageo, tsuka-ito, and blade make this a cohesive set suited for wall display or stand presentation. Each component is finished to match, producing a unified piece rather than a mix of generic parts.
