I can’t imagine trying to open a can of, well… anything without a can opener. A sturdy knife may be able to do the job but I’m more likely to stab myself severely than open the can. Fortunately, this problem is readily solved with the simplest of devices: a manual can opener. You know, the kind you actually use your hands to turn the knob. Since they’re so cheap at your local Walmart, pick up a few and toss them in your emergency preps and forget about them. They’ll last forever if not abused and are certainly better than being accidentally stabbed with a knife.

Since they’re so inexpensive and lightweight, pick up several and include them on your key-chains, in your bug out bags, and your vehicle kits.
