If chucks are to be accepted by modern law enforcement, it is important to eliminate stereotypes of the tool and understand how nunchaku relates to police needs. Nunchaku is a defensive tool that law enforcement can use to evaluate chucks. Police nunchaku training has developed into an officer defense system. Nunchaku training is more rapidly assimilated and more easily retained than other stick training. When cost and effect are considered, nunchaku training equals baton programs. In addition, blocking or trapping of chucks is all but impossible, and as much as 350 pounds of pressure per square inch can be created by the "pinching" technique common to most nunchaku restraints. Further, effective implementation of nunchaku requires only minimal user strength to produce maximum effect. Chucks greatly enhance officer safety due to their extreme range of defensive, offensive, and tactical applications. Approximately 60 police agencies have trained with nunchaku. As a martial arts technique, nunchaku training stresses restraint and control. This emphasis should eliminate negative stereotypes about it and improve the prospects for its use by police officers.
