History The Tonfa was developed as a weapon by the Okinawans, specifically for use in conjunction with karate. Two Tonfa were often used simultaneously, and were very efficient against armed assailants.
Traditional use: Originally a bean or rice grinder handle, the Tonfa’s circular movements as a farm implement evolved into its rotating strikes as a weapon. The side of the Tonfa was used for blocking, and the ends for direct punches.
Current use: Now an advanced karate training aid, the Tonfa aids in development block-and-strike strategies and upper-body strength. It is also used on many police departments throughout the United States.
