T10 Carbon Steel Katana with Hamon Blade, Black-Silver Tsuba & Black Lacquer Saya

The blade on this katana is ground from T10 carbon steel and finished to a polished chrome surface that reflects light cleanly along its length. A genuine hamon line runs the length of the edge - the visual result of the differential heat treatment process applied during forging. The full tang construction locks the blade solidly into the handle assembly, and the hand-finished edge runs from the base of the blade to a precisely tapered kissaki point. For collectors drawn to Flower Theme Blade Japanese Samurai Swords, the blade geometry here follows classical shinogi-zukuri lines.

The tsuka is built over a wooden core wrapped first in genuine white samegawa ray skin, then bound with black-and-white twisted ito cord in a traditional diamond pattern. Amber-toned menuki ornaments are set beneath the ito wrapping and appear through the open diamond windows along the grip. The fuchi and kashira fittings are finished in black to match the overall color scheme, and a red accent collar at the habaki transition adds a single warm note against the otherwise monochrome handle.

The tsuba is one of the most detailed components on this piece. Cast and finished in a black-and-silver palette, it carries an ornate scroll motif in raised relief across its entire face - silver engraving traces curved botanical forms against the dark ground. Gold-tone seppa washers on either side of the tsuba create a layered metal sandwich between blade and handle. The overall tsuba construction is consistent with the koshirae style specified for this sword.

The saya is shaped from hardwood and finished in matte black lacquer. The surface shows subtle tonal variation in the lacquer coat rather than a flat opaque finish. Real horn fittings are used at the koiguchi (scabbard mouth) and kojiri (scabbard tip), both visible as brown-toned accents against the black lacquer. The black-and-white sageo cord is attached at the kurikata and hangs in a loose braid, matching the ito color scheme on the handle.

This katana ships at a package weight of 4 lbs in a 43 x 4 x 4 inch box. Overall sword length is 41 inches with a 3 lb assembled weight. The koshirae-style fittings, full tang blade, and matched black-and-white color scheme across ito, sageo, and tsuba make this a well-coordinated piece for collectors focused on Black And Blue Katana and related dark-toned Japanese sword aesthetics.
