1090 Carbon Steel Black Blade Katana with Red Tsuka and Black-Red Lacquered Hardwood Saya

The blade is forged from 1090 carbon steel and given a bold black surface finish that contrasts sharply with the polished hamon line running along the edge. At 40.55 inches overall with a blade width of 1.259 inches and spine thickness of 0.275 inches, the geometry is well-proportioned for a 1090 Katana in the koshirae tradition. Full-tang construction means the steel runs uninterrupted through the handle, contributing to the sword's 2.8 lb balance point.

The tsuka is built over a PU black samegawa base, which provides the textured foundation beneath the dark red leather ito. The ito is wound in a traditional diamond-pattern wrap with evenly spaced black menuki ornaments visible at each crossing point, giving the grip both visual rhythm and a secure hold across the 40.55-inch length.

The tsuba is cast from alloy in a multi-lobe silhouette - a sculpted form with concave segments radiating from a centered gold-tone oval accent. The black finish on the tsuba body sets off the gold detail cleanly, and the overall shape bridges the dark blade and the red handle with deliberate visual weight.

The saya is shaped from hardwood and finished with a gloss black lacquer coat. Evenly spaced red stripe accents wrap the length of the scabbard, creating a bold graphic contrast that echoes the red ito on the handle. A dark red sageo cord is knotted at the koiguchi in a multi-loop decorative arrangement, completing the Black Hardwood Japanese Samurai Swords aesthetic with consistency across every component.

At 2.8 lbs and 40.55 inches overall, this katana carries enough presence for display while remaining manageable for handling. The package ships at 3.3 lbs in a 42.9 x 3.9 x 3.5 inch box. Note: sword stand is not included.
