 * Description: "Katana" is the general description of any Japanese sword or bladed weapon that is longer than a dagger. They vary in size, shape, and even in material. Katana, when used, often become the central focus of the ninja's jutsu, with the sword-user developing techniques to maximize his sword's efficiency.
 * Traditional use: In tradition, a katana is a single-edged sword designed for open-field combat. The blunt end of the katana could be, technically, used as a bludgeon tool. The forging of a katana can take over half a day, and is still considered an art in today's society. Katanas are not made for precise cutting-related attacks, since it could damage the blade. Wakizashi, a name given to swords with a blade length in-between that of a katana and a dagger, complements the use of a katana. The wakizashi is used where the katana could not, including executions and seppuku, ritual suicide, as such precise actions can dull or snap the katana's blade.
