You will never have to handle sharp lids from canned foods with your bare fingers again once you have this nifty can opener with Safety Lid Lifter. So simple to use, just place the opener on the can, line up with the rim and steadily turn the crank knob in a clockwise direction. The cutter will do its work and the lifter will grip the lid, ready for you to lift off and discard. Turn the knob in an anti-clockwise direction to release the metal lid then use the integrated mini-pliers to lift the cut disk for disposal. The opened can will have no sharp edges.Note: Stop cutting once the cutting circle is complete. This item is intended for domestic use only.
