A club (also known as cudgel, baton, truncheon, cosh, nightstick, or bludgeon) is among the simplest of all weapons. A club is essentially a short staff, or stick, usually made of wood, and wielded as a weapon since prehistoric times.Most clubs are small enough to be swung in one hand although two-handed variants are known. Various kinds of clubs are used in martial arts and other specialized fields, including the law-enforcement baton. The military mace is a more sophisticated descendant of the club, typically made of metal and featuring a spiked, knobbed or flanged head attached to a shaft.The wounds inflicted by a club are generally known as bludgeoning or blunt-force trauma injuries.
