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. The Tonfa is held in the hand with the length lying along the underarm. When choosing a Tonfa, holding the handle, the length should just reach past your elbow. The Tonfa is an excellent weapon for both defensive and offensive techniques, as it provides protection for the arms against striking weapons, and at the same time this weapons can be used or striking, with both the shorter and the longer end.
By spinning the tonfa around the short handle, a great tremendous striking force may be generated. By using the long portion in conjunction with the short handle, the tonfa may be used for arm locks or to control an opponent. When held by the handle and flipped with speed and power, the tonfa has the same deadly potential as a baseball bat or a club moves faster, and is easier to control so watch out.
