Stabbing

A stabbing is penetration or rough contact with a sharp or pointed object at close range. Stab connotes purposeful action, as by an assassin or murderer, but it is also possible to accidentally stab oneself or others. Stabbing differs from slashing or cutting in that the motion of the object used in a stabbing generally moves perpendicular to and directly into the victim's body, rather than being drawn across it.

Stabbings have been common among gangs and in prisons because knives are cheap, easy to acquire (or manufacture), easily concealable and relatively effective.
