Most people don’t carry a P 38 can opener in their pocket every day. This is a brilliant and simple trick that may very well save your life one day if you find yourself short-supplied. You can open a can without the help of a can opener and it’s easier than you might think. Just be careful.
Step One: Rub the can on the “rolled lid” side against any abrasive surface like concrete or asphalt. If you’re in the woods, a large rough rock will do the trick.
Step Two: Use a knife to open the can.
Simple, right?
