Product Details

This blue katana features a clay tempered spring steel blade measuring 28.74 inches with a hardness of 58 HRC. The deep blue finish across the nagasa is contrasted by a bright, jagged hamon line running the full length of the edge, creating a vivid visual separation between the hardened cutting edge and the tempered spine. The blade arrives with a hand-finished refined edge and a chrome-toned polish that catches light along its curves.

The 10.23-inch tsuka is wrapped in black cord over genuine white rayskin, providing both a traditional aesthetic and a textured, secure grip. The cord is tightly wound in a classic diamond pattern, and the rayskin nodes are visible beneath the wrapping, confirming authentic samegawa construction throughout the handle.

At the heart of the fittings sits an alloy tsuba with a detailed snake motif rendered in gold and silver tones. The openwork design features serpentine bodies winding through a geometric lattice, with fine surface detailing on both the gold and silver portions. This is one of the most visually dense guards you will find on a Blue Katana at this level.

The saya is constructed from hardwood with a piano lacquer surface in a textured blue-black pattern that echoes the blade's color. A braided sageo cord in black and blue tones wraps around the kurikata, complementing the overall dark-blue color scheme. The saya measures 30.7 inches and fits the blade snugly with a satisfying click at the habaki.

At 40.94 inches overall and 4.4 lbs, this is a full-size katana with real presence on a wall mount or display stand. Every fitting - from the snake tsuba to the piano lacquer saya - is coordinated around a deep blue and gold palette, making it a standout addition to any Real Katana Sword collection. Please note that the sword stand is not included.
