The Good Grips Snap-Lock Can Opener is as functional as it is elegant. Squeeze the Can Opener closed and hear the lock snap shut to hold the can securely while you turn the knob. There's no need to grip tightly to keep the Can Opener in place on the rim. Press the lock open with your thumb and it springs open to release the can. The curved handles of reinforced plastic are broad and rounded to distribute the pressure evenly across your hand as you squeeze. The oversized knob makes turning comfortable and easy.
