1095 Carbon Steel Katana with Black Blade, Green Cord Handle & Flower Tsuba - Koshirae Style

The blade of this katana is forged from 1095 carbon steel, finished with a striking black treatment that runs the full length of the 40.55-inch profile. A visible real hamon traces the edge, created during the hardening process and clearly defined against the darkened steel surface. The full tang construction extends through the handle, keeping the blade and hilt firmly integrated at 2.8 lb total weight. Collectors who appreciate Marble 1095 Carbon Steel Katana options will find this black-blade build a sharp contrast in aesthetic direction.

The tsuka is built over a hardwood core wrapped in PU black samegawa - a synthetic ray-skin material with a tactile pebbly surface. Over it, green cord ito is wound in the traditional diamond pattern, creating a secure, non-slip grip with clear visual contrast against the dark underlayer. Gold-tone menuki accents are visible beneath the wrapping, adding a subtle metallic detail to the handle construction.

At the blade-handle junction, a silver-tone alloy tsuba takes center stage. Its silhouette follows a lobed, multi-petal outline, and both faces carry engraved flower and botanical motifs - delicate petal clusters and leafwork spread across a hammered background texture. The silver finish ties directly into the bright polished bevel of the blade below it, creating a coherent metal palette at the guard.

The black hardwood lacquer saya provides a clean, gloss finish that echoes the blade's own dark tone. Silver-tone alloy kojiri and koiguchi fittings bookend the scabbard, while a shirasao-style band with additional floral engraving wraps the mid-section. A light green sageo cord is tied at the koiguchi, mirroring the handle wrap color and completing the green-black-silver color scheme across the full piece. For collectors drawn to this saya style, the Black Sunflower Tsuba Japanese Samurai Swords collection offers related koshirae configurations worth exploring.

Overall dimensions are 40.55 in length by 1.259 in blade width by 0.275 in spine thickness, with a shipping weight of 3.3 lb. The koshirae-style mounting presents this piece as a complete, display-ready assembly - blade, handle, tsuba, and saya all finished and fitted. Sword stand not included.
