Classified as a "Yokozuna" (demon sword), this sword is forged from manganese steel that can bend 90 degrees without deforming. The blade features blackened finish and traditional Japanese "Sashihone" (push-grinding) technique with double lines, resulting in a hardness of 60 HRC, capable of cutting through iron without damaging the edge. The sword measures 103 cm in total length, with a 71 cm blade, 26 cm handle, 3.2 cm blade width, and weighs 1.2 kg. The fittings include a zinc alloy tsuba, real wood lacquered scabbard with elegant sageo, and comes with a premium brocade box.
