How to use a camp can opener
Hold the can opener securely with your finger gripping the flat surface of the can opener (not the blade).
Your index finger should fit between the other side of the flat surface and the back of the small blade.
Camp can openers are made for use with the right hand.
If you are left handed, make sure you are comfortable using your right hand to open the can, or you may be cut by the blade. Hold the can firmly with your left hand.
