Blue Blade Katana in Manganese Steel with Lightning Engraving & Snake Tsuba

The blade is forged from high manganese steel and finished in a deep dark blue tone that shifts with the light. A hand-engraved lightning motif runs along the flat from the kissaki toward the habaki, creating a jagged, electrified visual line that pairs with the visible hamon running the blade's edge. Full-tang construction ensures the blade extends completely through the handle assembly.

The tsuka is built on a hardwood core wrapped in black PU samegawa for grip texture, then bound with black cord ito in a traditional diamond pattern. The fuchi and kashira carry a clean silver finish that bridges the dark handle wrap to the metalwork below. Two black menuki details are set beneath the cord wrap.

The tsuba is the defining feature of this koshirae - a silver coiled snake cast in detailed relief, its scales and head rendered with fine surface texture. A rectangular gold-tone seppa sits beneath, framing the guard against the blade's blue tones and contrasting the silver serpent casting. This piece fits naturally alongside other distinctive guard designs in our Full Tang Blue Katana collection.

The saya is shaped from hardwood and finished in a deep teal-blue lacquer that closely mirrors the blade's coloration. A braided sageo in blue and gold is tied at the kurikata in a full koshirae knot, adding textural contrast against the smooth lacquer surface. The cord's woven construction and tassel ends reflect traditional saya dressing.

At 41 inches overall and 3 lbs, this katana is sized for display mounting or shelf presentation. The coordinated dark blue, silver, and gold palette runs consistently from blade to saya, making it a cohesive centerpiece for any collection.
