History
The tonfa (side-handle baton) 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.
There is in principal only one kind of Tonfa although the shaft varies in shape from round to rectangular. History has also shown the butt ends to be pointed but this is extremely rare. The weapon attracts two kata in the Ryukyu Kobujutsu syllabus but because of its exposure with the police in the baton form it is a very popular weapon to practice with.
The weapon is used in pairs and is of wood, again red oak or white oak preferably in keeping with the Bo. The length of the weapon is also the same requirements as the Sai, about three centimetres past the elbow when gripped. The weight like the Bo is paramount to the efficient usage of the weapon. Too light and it lacks power in Kumite, too heavy and the techniques lack speed and become ponderous. Again like the Sai there are three grips, Honte-Mochi (Natural), Gyakute-Mochi (Reverse) and Tokushu-Mochi (Special grip). The latter is not commonly used but is very effective and relates strongly to the techniques of Kama.
Traditional use
Originally a bean or rice grinder, 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 development of block-and-strike strategies and upper-body strength.
