Product Details
The blade is T10 carbon steel, clay tempered using the traditional Japanese technique of applying clay unevenly before heat treatment. The thinner clay near the edge cools faster during quenching, producing a harder cutting zone, while the thicker clay along the spine retains flexibility. The visible hamon line runs along the polished surface as an organic, wavelike boundary that shifts appearance with viewing angle. T10 steel contains added tungsten for improved wear resistance and edge retention beyond standard carbon steels, and the blade reaches a hardness of 58 HRC.;
The tsuka is wrapped in black ito cord over ray-skin samegawa, built on a full tang foundation that runs the entire length of the handle. At 6.5 inches, the grip provides comfortable two-handed positioning. The black cord sageo is tied at the scabbard mouth in a traditional knot pattern, complementing the monochromatic palette.
A bronze-tone alloy tsuba with an orchid theme serves as the visual bridge between handle and blade. The orchid motif carries classical East Asian symbolism, and the detailed casting work is accented by gold-finished fuchi and kashira fittings that frame both ends of the handle. These small metallic details create a refined contrast against the otherwise all-black build.
The black hardwood saya features a matte finish with hand-engraved floral and branch artwork etched directly into the surface - visible in the main image as delicate gold-toned illustrations along the scabbard body. This engraving craft elevates the scabbard from a simple protective sleeve into a display piece in its own right. For collectors drawn to this style, the Black T10 Carbon Steel Katana collection offers additional options in similar dark aesthetics.
Overall length measures 41 inches with a 21.5-inch blade, weighing 3 lbs fully assembled. The all-black color scheme - from blade to cord to saya - gives this katana a cohesive, understated presence that works as a standalone wall display or as an anchor piece in a broader collection. Those interested in the clay tempering process behind the hamon can explore the full Clay Tempered Katana selection. Sword stand not included.
