Consisting of a straight, extending club, mostly used by security guards and police, they serve many purposes, such as riot control and criminal arrests. They still have their use today.
Although not very powerful, it has an extremely fast swing speed. Probably best used against opponents who aren't armed with melee weapons themselves as they will often block, stunning you for a few precious seconds. For this reason it's best to use V.A.T.S. attacks on other melee opponents.
