Ninjato Straight Katana in Manganese Steel with Blue Crackle Blade - Black Lacquer Saya, Wave Tsuba

The blade is the centerpiece of this straight ninjato, crafted from manganese steel with a hand-finished blue crackle surface that covers the full length from base to tip. The geometric pattern - fine white lines over deep cobalt - gives the steel a distinctive visual identity that sets it apart from conventional finishes. The blade runs full-tang through the handle, with an overall sword length of 41 inches and a finished weight of 3 lbs. If you are exploring the Blue Blade Manganese Steel Ninjato category, this piece is one of the more visually refined options available.

The tsuka is built with a black PU samegawa foundation wrapped in black leather ito using a standard diamond cross pattern. The binding is tight and even from habaki to kashira, with no loose sections at the turns. A silver-toned kashira caps the butt end, completing the all-black handle in a clean, consistent finish.

The iron tsuba is the most graphic element on this sword - a black-and-white wave design with flowing relief lines that create a sense of motion around the blade. The contrast between the white wave pattern and the black iron base is sharp and intentional, providing a visual bridge between the blue crackle blade and the black handle components.

The hardwood saya is finished in high-gloss black lacquer with no visible seams or blemishes. A silver-toned kojiri reinforces the tip, while the kurigata features a circular kamon medallion in white-on-black - a refined detail that adds collector-level identity to the scabbard. The black sageo cord completes the mounting in a consistent monochrome palette. For a broader look at the category, the Real Ninjato collection covers additional configurations.

At 41 inches overall with a 4 lb shipping weight and packaging dimensions of 43 x 4 x 4 inches, this ninjato is proportioned for wall display or case mounting. Each piece is individually handmade by experienced swordsmiths, so minor variations in surface detail from unit to unit are expected. Sword stand not included.
