Whip
A whip is a flexible device with a contact area that is used to inflict pain upon impact with the skin. The most common whips are bull whips (a la Indiana Jones) which were traditionally used for farming to keep cattle under control, horse whips such as riding crops and the longer dressage whips and floggers.
