This article is about the well known Japanese sword. For the character that goes by a similiar name, see Kitana.
A katana is a Japanese single-edged sword, developed between the Heian era to the Edo era. A katana was forged by a sword smith who smelted Japanese sand iron, called Tamahagane, removing impurities by folding the blade over and over. Katana were known for being incredibly sharp and versatile weapons, though they have to be meticulously taken care of. Katanas were used by the samurai of ancient and feudal Japan.
The ancestor to the katana, the tachi, was a long cavalry sword worn edge down, accompanied by a shorter sword called the uchigatana, in a manner similar to the wearing of the daishō, the katana and the wakizashi.
