History: Present in Okinawan and other Asian weapon arsenals, the sai (pronged truncheon) was used to stab, block, trap and punch. Practitioners often carried a sai in each hand, and a “spare”‘ at the belt. The weapon could also be thrown.
Traditional use: The sai is believed to have originated with the pitchfork. As a weapon, it was used in conjunction with various karate stances and techniques, and in defense against sword attacks.
Current use: With dulled points, the sai is now a karate training weapon. It tests accuracy in striking and quick block-and-counter techniques.
