Black Blade Katana in Manganese Steel with Chrysanthemum Tsuba - Full Tang Samurai Sword

The blade of this katana is forged from manganese steel and finished with an all-black treatment that runs edge to spine, creating a sleek, mirror-like silhouette against the light. At 40.5 inches overall with a 1.26-inch blade width, the proportions follow traditional katana geometry. The construction is full tang throughout, ensuring the steel runs the complete length of the handle for solid, uninterrupted structure.

The tsuka is wrapped in black cord over a black ray-skin (samegawa) base, using a traditional diagonal cross pattern that provides both grip texture and visual depth. Gold-tone menuki hardware is set into the wrapping at measured intervals - a small but deliberate contrast against the otherwise all-black handle that references classical Japanese sword fittings.

The tsuba is the visual centerpiece of this koshirae. Cast in iron with a cutout four-lobe silhouette, it carries a chrysanthemum motif in white and gold against a black body - an emblem historically associated with the Japanese imperial family. The contrast between the dark iron and the gold-tone center medallion gives the guard an authoritative presence that anchors the entire sword's design.

The saya is constructed from hardwood finished in natural black lacquer, producing a smooth, high-gloss surface that complements the blade's own finish. The black sageo cord is laced through the kurikata in a traditional knot pattern, completing a fully unified all-black koshirae. This consistent color language across blade, handle, guard, and scabbard makes it a strong candidate for display alongside other pieces in a Black Sageo Japanese Samurai Swords collection.

Overall length is 40.5 in, blade width 1.26 in, blade thickness 0.275 in, and total weight 3.17 lb. Each sword is individually handcrafted, so minor variations in finish and fitting may occur between pieces. Sword stand is not included.
