T10 Carbon Steel Katana with Real Hamon - Black Saya, Gold-Black Samurai Tsuba, Black-White Ito

The blade on this katana is forged from T10 carbon steel and hand-finished to bring out a visible hamon line along the edge. The steel is treated for hardness and durability using traditional swordsmithing methods, and each piece is worked individually - meaning minor variations in the hamon pattern are a natural result of the process, not a defect. The full-tang nagasa measures 40.5 inches in overall length, 1.26 inches wide at the base, and 0.275 inches at the spine, with a total weight of 3.2 lbs. If you're exploring other T10 builds, the Chocolate T10 Carbon Steel Katana collection offers additional finish options in the same steel category.

The tsuka is wrapped in black-and-white ito over a PU samegawa base, using a traditional diamond pattern that provides a firm, even grip surface. Alloy fittings in a matching finish hold the wrap securely at both ends. The black-white sageo cord at the saya mouth ties the handle and scabbard together visually and functionally.

The tsuba is cast alloy in a gold-and-black finish, shaped in a round koshirae style with a samurai-theme relief - figures and foliage carved into the surface with a small floral mon motif at the center. The gold tone creates a sharp accent point between the polished blade and the matte-black handle wrap.

The saya is built from hardwood and finished in a black natural lacquer coat, producing a smooth, deep gloss that fits the blade snugly. The lacquer surface is consistent across the full length of the scabbard. For collectors interested in black-finished builds, the Black Handmade Katana collection groups related pieces by this colorway.

Overall dimensions: 40.5 in length, 1.26 in blade width, 0.275 in spine thickness, 3.2 lbs. Shipping weight is 4.4 lbs in a 43.3 x 3.9 x 3.2 inch package. Sword stand not included. Because each piece is individually handcrafted, minor spec variations between units are expected.
