Blue Manganese Steel Katana with Wave Hamon, Splatter Saya & Black Cord Handle

The blade is forged from manganese steel and finished in a deep, consistent blue that runs from the base to the tip. A hand-etched wave hamon traces the entire cutting edge, rendered as a pale undulating line against the blue body - a detail clearly visible in the close-up product shots. The full-tang construction ensures the blade extends completely through the handle, giving the piece solid structural integrity whether displayed horizontally or mounted on a stand.

The tsuka is wrapped in black cord over a PU blue ray-skin (samegawa) base, producing the two-tone black-and-blue handle visible in the image. The blue samegawa shows through the diamond-shaped gaps in the cord wrap, tying the handle color directly back to the blade. The handle dimensions follow traditional katana proportions and sit comfortably in scale with the 41-inch overall length.

The black iron tsuba features a geometric open-ring design - a circular frame with cut-out sections that keep the guard visually light while maintaining the all-black fittings palette. The menuki and collar (habaki) carry forward the same restrained metalwork, letting the blade and saya carry the color story of this piece.

The hardwood lacquer saya is the most visually unexpected element: a white base coat with a multi-color paint-splatter pattern in black, red, and white dots distributed across the entire length. This modern finish contrasts sharply with the clean blue blade and creates a collector-focused aesthetic that sets this katana apart from single-color scabbard designs. A black sageo cord is knotted at the koiguchi for traditional presentation. For more options in this color family, browse our Blue Blade Katana Sword collection.

This katana measures 41 inches in overall length and weighs 4 lb, shipping at 5 lb in a 43 x 4 x 4-inch package. The koshirae-style mounting - blade, tsuka, tsuba, and saya presented as a complete set - makes it a self-contained display piece. Note that a sword stand is not included.
