Manganese Steel Katana with Blue-White Blade, Mermaid-Engraved White Saya & Blue Tsuka

The blade on this katana is forged from manganese steel and finished in a blue-to-white gradient that shifts dramatically from kissaki to habaki. A hand-applied wave engraving runs along the flat of the blade, reinforcing the oceanic visual theme that carries through every component of this piece. The steel holds a clean, precision-finished edge with no visible hamon, letting the painted gradient and engraving work take center stage. If you are exploring the full range of Blue And White Katana options, this piece sits at the more artistic, design-forward end of the spectrum.

The tsuka is wrapped in blue cord over white PU samegawa, with the diamond-pattern lozenge windows exposing the faux ray skin beneath. The wrap is tight and evenly spaced from kashira to fuchi, and the blue sageo cord tied at the mouth of the saya matches the handle wrap color exactly. A carved fuchi collar in cream-toned material bridges the grip and guard without interrupting the color flow.

The tsuba is black iron with an ornate scroll cutout theme - four rounded negative-space lobes cut through the plate, framing a central raised boss embossed with a swirl motif in gold-tone detail. The black finish on the plate contrasts cleanly against the cream fuchi and the gradient blade, giving the fittings a composed, layered look rather than a busy one.

The saya is lacquered hardwood in solid white, and the standout feature is a large ink-style engraving of a mermaid figure rendered in black-and-white detail across the mid-section of the scabbard. The illustration style reads like traditional Japanese woodblock-influenced linework. For collectors building around White Scabbard Japanese Samurai Swords, the mermaid motif makes this saya one of the more visually distinctive options in the category.

Overall length is 41 inches and the piece weighs 3 lb, shipping at 4 lb in a 43 x 4 x 4-inch package. The full-tang manganese steel construction, ornate koshirae fittings, and illustrated white saya combine into a cohesive themed set suited for display or collection.
