How do you use good cook 4 in 1 can opener?

To use the Good Cook 4-in-1 can opener, first, position it on the can's edge and align the cutting wheel with the lip of the can. Squeeze the handles together to pierce the can and then rotate the handle to cut around the lid. Once the lid is fully cut, use the magnet on the opener to lift the lid off safely. Finally, you can also use the other functions, such as the bottle opener and jar grip, as needed.
