Avoiding ragged edges when removing the lid from an open can is tricky. By cutting below the edge on the side of the can, the Oxo Good Grips smooth edge can opener leaves no metal behind. You can even replace the lid for smart storage. The side-wind knob is easy to turn and has a comfortable non-slip grip. The hardened stainless steel cutting wheel doesn't come into contact with the can's contents, while built-in pliers allow for touch-free lid removal. Hand wash with soap and water.
