Manganese Steel Blue Blade Katana with Skull Tsuba in Gray Marble Saya - Full Tang

The blade on this katana is forged from manganese steel and finished in a striking deep blue, running the full length from the pronounced kissaki down to the habaki. A visible hamon line traces the edge, and a wave-pattern engraving runs along the back spine, giving the steel a layered, high-contrast look that stands out whether mounted or displayed flat.

The tsuka is built full tang, with white rayskin forming the base wrap beneath gray ito cord wound in the traditional diamond pattern. The grip seats firmly in both hands, with the cord tension consistent from collar to pommel. A matching gray sageo is tied at the kurikata on the saya.

The tsuba is cast from alloy in a skull motif - a sculptural design with a darkened finish and a gold-tone seppa that bridges it cleanly to the tsuka. The contrast between the dark skull casting and the gold accent reads clearly even at a distance, and pairs well with the blade's blue tone.

The saya is shaped from hardwood and finished with a premium natural lacquer in a gray marble texture - mottled light and dark gray across the full length. It accepts the blade with a secure, smooth draw. The gray sageo completes the monochromatic color story from handle to scabbard.
