Abstract: A carton opening device is provided for opening diverse types of cartons, for example, cartons held together by retaining straps, retaining wires and/or nails. The device comprises an L-shaped handle having a first and second leg. A crowbar claw is formed at the free end of the first handle leg while a diametric channel is formed across the free end of the handle second leg for engaging and breaking retaining wires on cartons. A substantially axial slot extends from the corner of the handle and terminates short of the free end of the handle second leg for engaging and breaking retaining straps on cartons.
