T10 Carbon Steel Katana with Real Hamon in Dark Red Lacquered Saya - Full Tang, Chrysanthemum Tsuba

The blade on this katana is forged from T10 carbon steel, a high-carbon tool steel prized for its hardness and edge retention. A genuine hamon line runs along the length of the chrome-finish nagasa, the result of differential heat treatment that leaves a distinct temper pattern visible against the matte-polished surface. The blade's geometry follows a traditional katana profile - gently curved, with a clean kissaki that tapers to a refined point. For collectors browsing our Red Katana Sword range, this piece sits squarely in the classical koshirae tradition.

The tsuka is shaped from wood and wrapped with brown cotton ito over PU black samegawa - the diamond pattern of the wrap is consistent and tight, with no loose sections visible along the grip. Two small gold kanji characters are inlaid into the ito midway along the handle, a detail that reads clearly in photographs and adds a layer of authenticity to the overall presentation.

The tsuba is a standout component. Cast from black alloy, it features a chrysanthemum theme with deeply carved petals radiating from a central boss. The fuchi and kashira fittings share the same dark copper-brown tone as the tsuka wrap, creating a cohesive color story from pommel to guard. The fit between tsuba and habaki is snug, with no visible gap around the blade collar.

The saya is built from hardwood and finished in dark red lacquer - the color reads as a deep burgundy in direct light, shifting toward crimson at the edges. The surface texture is slightly irregular in the way hand-applied lacquer tends to be, giving it character rather than the uniform sheen of a mass-produced piece. The brown sageo is attached at the kurigata and tied in a traditional braided knot at the saya mouth, with a small copper-tone bead seated at the center of the tie. Collectors interested in coordinated display setups will find more options in our Darkred Scabbard Katana collection.

Overall length is 41 inches and the assembled sword weighs 3 lbs. Shipping weight is 4 lbs in a 43 x 4 x 4-inch package. The sword stand is not included. This is a collectible replica intended for display and appreciation of Japanese sword craftsmanship.
