Brass knuckles, also sometimes called knuckles, knucks, brass knucks, or knuckle dusters, are weapons used in hand-to-hand combat. Brass knuckles are pieces of metal, usually steel despite their name, shaped to fit around the knuckles. Designed to preserve and concentrate a punch's force by directing it toward a harder and smaller contact area, they result in increased tissue disruption, including an increased likelihood of fracturing the victim's bones on impact. The extended and rounded palm grip also spreads across the attacker's palm the counter-force that would otherwise be absorbed primarily by the attacker's fingers, reducing the likelihood of damage to the attacker's fingers.
