chakraM

The chakram (Devanāgarī: चक्रम) is a throwing weapon that was used by the ancient Indians; it is a flat metal ring with a sharp outer edge from 5 to 12 inches (13−30 cm) in diameter. The word comes from Sanskrit and means round, circle, or wheel. Earliest references come from the Indian epics Mahabharata and Ramayana (here the Sudarshana Chakra is the weapon of the god Vishnu). It was used by Indian armies, mostly by Sikhs (who have it on at least one flag).It has an effective range of 40 to 50 meters. Because of its aerodynamic shape (similar to an aeroplane wing, Flying disc, or Aerobie), it is not easily deflected by wind.
