A whip is a firm, flexible stick, usually made of leather or other flexible material, or a stick with a piece of fabric or rope attached. Some types of whip may have multiple thongs and/or incorporate barbs, spikes, knots, or hooks, or may be plaited with wire. Sjamboks are a type of heavy whip traditionally made of leather but now also made of other materials, such as plastic.
Whips are often used to carry out corporal punishment. They can cause lacerations and other injuries, which may lead to permanent scarring. Lack of medical attention or unsanitary conditions can lead to infection. Their use amounts to excessive force or cruel or inhuman treatment, possibly amounting to torture, as they cannot be used without inflicting excessive and unnecessary pain therefore they should not be manufactured, traded, or used by law enforcement.
