Brass Knuckles are metal devices with holes punched through them, and are thus intended to be worn on the fingers while the fist is clenched. They are meant to increase the force of a punch, while minimizing the initial force needed to throw an arm, and when used properly, they create massive damage against an intended target. Brass Knuckles have been available in Grand Theft Auto: Vice City, Grand Theft Auto: San Andreas, Grand Theft Auto: Liberty City Stories and Grand Theft Auto: Vice City Stories. In each game, the force of a single Brass Knuckle punch is enough to knock a person to the floor.
