T10 Carbon Steel Katana with Real Hamon in Red Marble Lacquer Saya - Brown Cord Handle

The blade is ground from T10 high-carbon steel and finished to a bright chrome polish that makes the hamon immediately visible along the entire length. Clay tempering creates the distinct temper line where the harder edge zone meets the softer spine - a process that leaves each blade with a slightly unique hamon character. At 40.55 inches overall and 2.8 lb, the geometry is proportioned for a full-sized katana silhouette. If you are exploring other high-carbon options, the Darkred Katana collection brings together builds that share this same bold color direction.

The tsuka is assembled over a full-tang nakago and wrapped in brown cotton cord ito using a traditional diamond-gap pattern over PU white samegawa. The white ray-skin panels show clearly through the wrap gaps, creating a high-contrast visual rhythm down the handle. Brown cord offers a firm, slightly textured feel that keeps the grip stable during extended display handling.

A round black iron tsuba with symmetrical hollow cutouts sits at the blade junction, keeping the guard profile clean and uncluttered. A gold-tone menuki accent is set into the tsuka beneath the wrap, and a brass habaki collar secures the blade-to-handle fit. The fittings follow a koshirae-style assembly with coordinated metal tones across all collar and collar-adjacent components.

The hardwood saya is lacquered in a marble style - deep red as the dominant ground color with irregular black splash patterning dispersed across the surface. The lacquer coat produces a semi-gloss finish that gives the scabbard visual depth. A brown-blue mixed sageo cord is threaded through the kurikata and tied in a traditional bow, adding a two-tone accent that bridges the brown handle and red saya. For collectors interested in how this colorway fits a broader aesthetic, the Multi-colored Katana collection showcases similar mixed-palette builds.
