Both Samurai and commoners alike considered the Sensu (folding hand fan) an important accessory. Customarily carried in the hands or tucked in the obi (belt), the Sensu also played a significant role in Japanese etiquette, especially on formal occasions, and was rarely ever out of a Samurai's possession.

The Tessen, are constructed of either an actual folding fan with metal or bamboo ribs, or a non-folding solid bar of either iron or wood and shaped like a folded fan. It usually has eight to ten ribs and could be worn with everyday attire. There were many situations in which a Samurai would not be allowed to wear a sword. A Tessen, though, was acceptable in any situation, thus leaving the Samurai always armed with at least one very effective defensive weapon. In training, a short wooden stick is also used to resemble the Tessen.
