Abstract: A can opener includes a pair of pivoted handle members (101), (102), associated with a drive wheel (108) and a cutting wheel (111), which are brought into a position to nip the rim of a can when the handles are closed. The nip on the can is not lost when the handle members are partially opened to an intermediate position. As shown the cutting wheel is pivotally mounted on a rotatable carrier (112) in the handle (101) and has a projection (104) entering a recess (105) in the handle (102). The recess allows the handle (102) to move between the closed and intermediate positions without disturbing the carrier (112). Closing the handle (102) drives a drive shaft (110) carrying the wheel (108) through gearing (153), (154), (155). A one-way clutch spring (116) slips when the handles open so that repeated opening and closing of the handles cuts round the can.
