An electrically operated knife includes a handle and a first set of dual cutting blades connected together for reciprocal side-to-side linear motion. A first stationary motor connected to a power source and a first reciprocating assembly is removably connected to the first set of dual cutting blades and coupled to an output shaft of the first motor for reciprocally moving the first set of dual cutting blades. There is a second set of dual cutting blades mounted in spaced relationship to the first set of dual cutting blades. A second motor and a second reciprocating assembly are provided for reciprocally moving the second set of dual cutting blades. A mounting member and a pivotable lever are provided for selectively adjusting a spaced relationship between the first set of dual cutting blades and the second set of dual cutting blades and a switch which operates both motors.
