The chotta Chakkar or chakram (the small ring) is a steel ring 5 - 12 inches in diameter of varying thickness. When used in battle, it usually has a sharp outer edge, but for ceremonial purposes the outer edge is left blunt. It is classified as a quoit-type weapon which is thrown or hurled, either by being released after being twirled around the smooth inside edge by the forefinger (a favourite Sikh method) or released frisbee-like or discus style. It has an effective range of 40 to 50 metres. * The above article based on What the heck is a Chakram, anyway?
