T10 Carbon Steel Katana with Clay Tempered Hamon Blade - Black Matte Saya, Brown Cord Handle

Product Details
The blade is forged from T10 carbon steel and clay tempered to produce a well-defined hamon running the full length of the cutting edge. The differential heat treatment hardens the edge while preserving flexibility in the spine - a process visible in the wavy temperline that distinguishes hand-finished work from machine production. The full tang construction runs the entire length of the tsuka, contributing to the sword's 2.8 lb balance and overall rigidity at 40.55 inches.
The tsuka is built over a wooden core wrapped first in real white samegawa - genuine ray skin prized for its raised nodule texture - then bound with brown ito cord in the traditional hineri-maki diamond pattern. White same nodes show through each opening in the wrap, creating the characteristic spotted rhythm seen on authentic High quality Samurai Sword mountings. The result is a handle that sits firmly in hand without surface slip.
The black iron tsuba carries an open geometric lattice design - a circular plate with evenly spaced radial cutouts that give it a light, architectural appearance without sacrificing structural presence. The cutwork pattern creates contrast against the white habaki collar and the brown cord wrap immediately behind it, tying the metal fittings visually into the overall color scheme of the koshirae.
The saya is shaped from hardwood and finished in black matte natural lacquer with a fine dark speckle texture across the surface. A brown and white sageo cord is knotted through the kurigata in a multi-loop decorative tie that matches the ito color palette and adds detail to the scabbard mid-section. The matte lacquer finish absorbs light rather than reflecting it, reinforcing the sword's restrained, traditional aesthetic.
At 40.55 inches overall with a blade width of 1.259 inches and spine thickness of 0.275 inches, this katana presents the proportions of a standard uchigatana in full koshirae dress. The combination of T10 steel, clay tempering, ray skin handle, geometric iron tsuba, and lacquered hardwood saya makes it a cohesive collectible piece for display or study of traditional Japanese sword furniture.
