Did You Forget The Can Opener Again?

SHARE

Have you ever headed out for a nice weekend of camping only to end up frustrated and hungry because you forgot one little thing… a can opener? Fortunately there is a little trick that lets you open up any tin can with nothing more than a rock.

Modern cans are sealed using a roller that bends the top of the can over the wall and the bends it again to form a leak proof crimp in the can. This leaves only a small amount of metal around the top lip of the can that actually seals the contents.

If you ever find yourself without a can opener simply find a large flat rock or piece of concrete, the rougher the better.  Simply place the can upside down on the rock and press down slightly.  Begin sliding the can back and forth across the rock until you begin to see moisture from the contents being left behind.

Once you see the juice, it means that the seal on the can has been broken and you should be able to use a knife or other sturdy utensil to pry the top of the can off.  If you are not concerned with saving water and only want the food, you can keep sliding the can across the rock to further erode the seal and make opening the can easier.

This is a much safer alternative than trying to hack away at the can with your pocket knife and if you apply the right amount of pressure should take you less than a minute open.

Do you have any other alternative tips for when you don’t have the right tool for the job at hand?

Nicely done, I wasn’t aware of this. Makes my old stab-a-circle approach seem undignified, to say a least. :)

I have a little Gerber multi-tool that I keep in my pocket all the time. It is only about an inch wide and about 2.5 inches long. It has a can opener on it and I’m almost never with out it. I like your solution too. I’d never tried that way to open a can.

I always carry my trusted P38. It is the first one I got with my rations in VietNam.

I taped one p38 to the top of a can inside each case of stored food, one on my key ring and one in my bug out bag. These cost about $.40 each so you can afford to have them in several locations. I like the new method when even my multiple locations are not available. Good hint.

I don’t see many flat rocks or sidewalks when I’m out in the sticks.

The old p38 on my key ring was transfered from my dogtag chain in 1957 when I was discharged. It has served as a screwdriver, both slot and phillips all these years and has opened many cans. It was good for breaking down an M1 into the three major parts for cleaning. Indispensible tool for a few hours or many days in the woods or on the water. A never fail can opener that is very small, very light and VERY durable.

The old P38’s were made of much better metal but the new ones will do the job. They were called p38’s because it took 38 whops to get around the world war 2 rations.

Wouldn’t it work just as well to keep the can right-side-up and rub the stone on the top of the can? Then you would not lose any of the juice.

I like this idea, it seems much easier than opening one with a spoon and a safer option then trying to open a can using a pocket knife.

For years there have been Swiss style pocket knives with a can opener (for punching a hole in a can) and a tiny saw blade, a regular blade, tiny scissors, tweezers, and a toothpick. Who needs a separate can opener or a stone when all this is available in one pocket knife?

Donna, You will wish for a stone if you ever survive a plane crash and there is nothing to eat except can food. You are not allowed anytype of knife in a plane. By the way, do you own a Swiss pocket knives? very few people do, but all need to eat.
