Blue Blade Katana in Manganese Steel with Dragon Tsuba, Teal Ito & Blue Lacquer Saya

The blade on this katana is forged from manganese steel and finished in a deep, uniform blue - a color treatment that doubles as a protective layer while giving the sword its most recognizable visual character. Running along the edge is a hand-etched wave hamon, a sinuous white line that traces the full length of the nagasa and stands out sharply against the blue finish. At 40.5 inches overall with a blade width of 1.26 inches, the geometry is true to traditional katana proportions.

The handle assembly follows a classic koshirae construction. White synthetic samegawa (ray-skin) forms the base layer beneath a teal ito wrap, with the cord woven in the traditional diamond-gap pattern that exposes the samegawa beneath each crossover. Bronze-tone alloy menuki and fittings tie the hardware together, warm against the cooler blue-and-teal color scheme. Full tang construction runs the blade continuously through the handle for solid structural integrity.

The tsuba is the focal point of the fittings - a circular bronze alloy guard with high-relief dragon figures sculpted across its face. The dragons wrap the guard's rim with detailed scales and open mouths, rendered with the kind of surface depth that rewards close examination. The rectangular seppa plates on either side are finished in matching gold tone.

The saya is crafted from hardwood and finished in a deep blue lacquer that mirrors the blade's color precisely, creating a unified aesthetic when sheathed. A blue-and-white braided sageo cord ties at the saya's kurikata, adding a traditional finishing detail.
