1095 Carbon Steel Katana with Dark Red Lacquer Saya - Full Tang, Blue Cord Handle, Chrysanthemum Tsuba

The blade is crafted from 1095 carbon steel with a manganese steel composition, ground to a 28.74 in. nagasa and hand-finished to a high-polish chrome surface. A real hamon line runs the length of the edge, the result of differential heat treatment that leaves a visible temper pattern - a detail that separates this piece from decorative replicas with painted or acid-etched lines. Blade hardness is rated at 62 HRC, and the edge is hand-finished. For collectors interested in the full range of Darkred 1095 Carbon Steel Katana options, this piece sits at the sharper end of the display-grade spectrum.

The tsuka runs 10.62 in. and is built on a full tang core, meaning the steel extends through the entire handle without interruption. The wrap is dark blue cord applied in a traditional diamond pattern over genuine black rayskin (real samegawa) - not synthetic PU. The rayskin's natural pebbled texture adds grip and tactile authenticity, and the contrast between the dark blue cord and the white diamond windows gives the handle a precise, layered look consistent with what is visible in the product images.

The tsuba is cast from alloy in a chrysanthemum silhouette with a black body and gold-tone center detail. The flower-form cutouts frame the habaki and add visual depth at the transition point between handle and blade. This is one of the more recognizable classical motifs in Japanese sword fittings, and the black-gold colorway ties directly into the handle's dark tones.

The saya is made from hardwood with a matte natural lacquer finish in dark red. At 29.92 in., it fits the blade with a tight draw. The braided blue sageo is knotted at the koiguchi, and a small red accent bead is visible at the knot - a detail confirmed in the product images. The contrast between the deep red saya and the blue sageo is the defining visual signature of this piece. Browse the broader Blood Red Katana Sword collection for related colorway options.

Overall length is 40.55 in. and weight is 2.8 lb. The koshirae-style assembly - rayskin handle, lacquered hardwood saya, alloy tsuba, and polished blade - is presented as a complete matched set. This katana is designed for collectors and display enthusiasts who want accurate construction details and a strong visual presence on a wall mount or sword stand.
