The Advanced Tamahagane Katana is a single-edged, curved long sword. It has the Tamahagane kanji manufactured into the left side of the blade in front of the Tsuba or guard. They come with a Saya or scabbard that matches the Tsuka-ito (wrap of the handle) of the sword. The basic Tsuka-ito is made of cotton. The blade is manufactured under very strict guidelines using equipment purchased from Ketsurui Zaibatsu. The monomolecular edged blade gives the weapon greater penetration and damage.
