Manganese Steel Katana with Blue Blade in Dragon-Theme Saya - Black & Blue Samurai Sword

The blade on this katana is forged from manganese steel and finished in a deep blue coating that runs the full length of the nagasa. A visible hamon line traces the edge, where the silver steel breaks through the blue finish to create a serrated, wave-like border between the polished edge and the colored spine. The result is a blade that reads as visually dynamic from any angle, with the blue-to-silver transition doing most of the visual work without any added ornamentation.

The tsuka is wrapped in black ito cord over a white PU same-gawa base, following a traditional diamond-pattern wrap that exposes the ray-skin beneath at regular intervals. The wrap is firm and even, with the black-and-white contrast giving the handle a crisp, structured appearance. This is a standard full tang configuration - the blade steel extends through the handle for structural integrity appropriate to a display piece of this size.

The tsuba is cast iron in black, featuring a round profile with geometric open-work cutouts arranged symmetrically around the blade slot. A small gold-tone menuki sits at the center of the habaki side, providing a single warm accent against the otherwise monochromatic fittings. The geometric cutout pattern keeps the guard visually light while maintaining a strong silhouette.

The saya is where this katana makes its most distinctive statement. The hardwood core is lacquered in a multi-color dragon-theme finish - layers of teal, cyan, black, and gold create a marbled, painterly surface that suggests movement and scale texture without depicting a literal figure. A braided sageo cord in navy blue and gold is knotted at the kurigata, picking up the saya's color tones and tying the overall palette together. If you're drawn to Blue Samurai Sword designs that go beyond a single solid color, this saya treatment stands out in any display context.

Overall length is 41 inches with a shipping weight of 4 lbs and packaging dimensions of 43 x 4 x 4 inches. This piece is part of the broader Handmade Japanese Sword line and is intended for collection display or cosplay use. Sword stand not included.
