T10 Carbon Steel Katana with Real Hamon - Blue Ito, Bronze Samurai Tsuba, Black Lacquer Saya

The blade is forged from T10 carbon steel and runs full-tang through the handle for a single-piece construction that keeps balance consistent from tip to kashira. Heat treatment produces a genuine hamon - the undulating temper line visible along the shinogi-ji is a direct result of differential hardening rather than acid etching, giving each sword a unique pattern. At 40.5 inches overall with a 1.26-inch blade width, the geometry follows classic katana proportions that collectors and iaido practitioners recognize immediately.

The tsuka is assembled over a hardwood core wrapped first in PU white samegawa - the raised, pebbled surface that traditional ray skin provides - then bound tightly in blue ito using a standard hishigumi diamond pattern. The alternating blue-and-white diamonds run the full length of the grip, and white menuki are set beneath the ito at their traditional positions, adding subtle relief under the hand. The kashira and fuchi are finished in matching dark metal tones that anchor the handle visually without competing with the blue ito.

The tsuba is one of the most detailed elements on this build. Cast in bronze with a dark patina ground, it features a raised samurai-figure composition with gold-tone gilding applied to the focal elements - visible in the close-up shot as warm gold against the darker iron-like surround. A single kozuka hitsu-ana is cut into the body on the ura side. The round form and figurative theme place this firmly in traditional koshirae style. Collectors interested in gilded guard designs can explore the full range in the Gold Printed Tsuba Katana collection.

The saya is shaped from hardwood and finished with multiple coats of premium natural lacquer, resulting in a deep black surface with a smooth gloss. The kurigata is positioned at the standard location for a two-piece sageo tie, and the blue-and-white braided sageo - matching the ito color palette exactly - is knotted through it in the image. The koiguchi fits the blade snugly, and the kojiri cap closes the tip cleanly.

Total weight is 2.78 lb with overall dimensions of 40.5 x 1.26 x 0.275 inches, shipping at 4 lb in a 42 x 4 x 4-inch package. The complete koshirae - blade, tsuka, tsuba, and saya - is included. Sword stand not included.
