T10 Carbon Steel Katana with Clay-Tempered Hamon Blade in Brown Ito & Black Hardwood Saya

The blade is forged from T10 carbon steel and clay-tempered, producing a genuine hamon - the undulating temper line visible along the edge that marks the transition between the hardened cutting edge and the softer spine. The resulting surface shows a hand-finished matte texture with subtle forge marks, giving the blade a character distinct from machine-ground steel. At 41 inches overall with a blade width of 1.259 inches, the geometry stays true to classical katana proportions.

The tsuka is built on a full-tang construction, wrapped in genuine white samegawa (ray skin) as the foundation layer. Over that, brown cotton ito is applied in the traditional diamond-wrap pattern, with white menuki ornaments seated beneath the crossings. The warm amber-brown tone of the ito creates a strong visual contrast against the pale samegawa diamonds, giving the handle a refined, two-tone appearance. A gold-tone fuchi collar adds a final accent at the blade collar junction.

The tsuba is a round iron piece finished in black, featuring an open latticework ring design with evenly spaced radial cutouts around the perimeter. This style keeps the guard visually lightweight while maintaining the structural role of hand protection. The black iron finish ties directly into the saya and sageo color palette, maintaining cohesion across the full koshirae.

The saya is shaped from hardwood with a matte black finish that carries a deliberately uneven, mottled texture - dark olive and charcoal tones blend across the surface for a weathered, organic look rather than a flat lacquer gloss. A dark brown and white braided sageo is knotted at the kurigata in a classic wrap, with the cord ends left to drape naturally. This Handmade Katana presents well both sheathed and drawn.

At 3 lbs and packaged in a 43 x 4 x 4 inch box, this koshirae-style katana suits collectors seeking a piece with genuine clay-tempered construction and coordinated brown-and-black fittings.
