Sai (weapon)

The sai (Japanese: , lit.'hairpin'; Chinese: , lit.'iron ruler', or Sau cha 手叉 lit.'hand-fork' in Cantonese) is a three-pronged melee weapon from Okinawa. It was historically utilized in martial arts such as Okinawan kobudō and southern Chinese martial arts, and has been absorbed into the curriculum of many modern martial arts. The sai is primarily used for striking, parrying and disarming opponents. It consists of a metal main prong, that projects from a one-handed handle, two shorter metal side prongs, which project from opposite sides of the base of the main prong and point in the same direction as it, and a blunt metal pommel fixed to the bottom end of the handle. The sai came to international attention when Okinawan kobudō and karate reached international popularity in the mid-20th century.
