Using a Manual Can Opener
1. Open the arms of the can opener. Place the metal tooth (the wedge) on the lip of the can. This will automatically align the wheel of the opener to where it needs to be. Firmly squeeze the arms together. With practice, you’ll be able to tell when it’s on right.
Until you get the hang of it, you may have to do it several times.
2. Start turning the handle when it fits securely. Otherwise, it could fly off the can. It is a sharp object, so you want to be careful. This begins to rotate the wheel underneath that then cuts into the can.
3. Work your way around the rim of the can as you turn the handle. This action pierces the seal, cutting into the can as it moves around the edge of the lid. When it has gone all the way around, the lid will naturally disengage from the opener. Carefully dispose of the cut lid. Enjoy the contents of the container.
