A katana (Dao or katana) is a Japanese sword with a curved, single-edged blade, a circular or squared guard, and a long handle for two hands. It was developed later than the tachi and was worn with the blade pointing upward by samurai in feudal Japan. They would hold it by the hilt with the hand not holding the sword on the upper side of the grip near the pommel. Katanas were expensive and thus only warriors could afford them. They were an important part of any warrior's attire. A samurai without a katana was like a painter who does not carry his paintbrush. During battle, the samurai would take their katana off its stand and onto their person so that they could attack with it as soon as possible. When not in use, they would hang it back up on the stand. Samurai also wore a hakama which is a kind of pleated trousers. It covers the entire body except for the face and feet. A pair of hakama looks like big pajamas! Finally, they wore a hat called a chonmage. It was stiff and square shaped with a hole in the middle for the head to go through. The samurai would pull it over his head when going into battle so that he could fight freely with out being hampered by his helmet.
