An opening device is described for cans having a tear-away closure panel that is defined by a circular score line adjacent the rim of the can, the panel being connected by a rivet to a ring tab lying approximately flush with the surface of the panel. The device has a generally circular perimeter, a handle opposite the perimeter, and a recess in the perimeter formed by a narrow mouth and two opposed prongs, the sides of at least one prong being separated by an acute angle. The opener is operated by wedging a prong beneath the ring tab to pry it upwardly and break the score line. Then the device is rolled toward the opposite side of the can, pulling the closure panel upwardly while continuing to break the score line until the closure panel is removed from the can.
