Handmade Japanese Katana in T10 Carbon Steel - Clay Tempered, Real Hamon, Black Saya, Full Tang

This handmade Japanese katana is forged from T10 carbon steel - a high-carbon alloy enhanced with tungsten for added hardness and edge retention. Through traditional clay tempering, the blade develops a real hamon: the visible temper line that distinguishes a differentially hardened blade from a uniformly treated one. It is this process that gives the steel its dual character - a harder edge paired with a more flexible spine.

The handle is built on a full tang foundation, wrapped in genuine white ray skin (samegawa) and secured with a tightly wound brown cord (ito). This layered construction is more than decorative - it provides the textured, non-slip grip that defines traditional katana handling. The fittings are premium metal throughout, maintaining a unified aesthetic from tsuba to kashira.

A black hardwood saya houses the blade, finished with real horn at the koiguchi and kojiri. The understated color palette - black saya, brown cord, white samegawa - keeps the visual focus on the blade itself, where the hamon line and hand-forged surface texture tell the story of the steel.

At 41 inches overall and 3.0 pounds, this katana sits comfortably within traditional proportions. It is the kind of piece that holds its own on a display stand or mounted on a wall, drawing attention through material quality rather than ornament. For those building a collection of clay tempered katanas or exploring the range of T10 steel swords, this is a solid anchor piece.

Hand forged by seasoned sword smiths using centuries-old technique, every element of this katana - from the clay-tempered blade to the horn-fitted saya - reflects a commitment to traditional Japanese craftsmanship. A meaningful addition to any collection that values authenticity and material integrity.
