Sudarshana Chakra

The Sudarshana chakra is Vishnu/Krishna's discus weapon, thousand-spoked and irresistible; the chief armament of the Lord's four-armed form and the emblem of His destroying power. At SB 1.8.13 Krishna protected the Pandavas of undivided heart 'svastrena', with this His own weapon, as the five blazing shafts of Ashvatthama's brahmastra advanced upon them.
