Now, I've never had this problem, because my GI pocket knife has a can opener blade in it, and in the service I had a P38 can opener on my key chain. Pop-top beer and soda cans, of course, pose no problem at all. We're talking normal tin cans with food in them here.

First, DON'T use a knife to "chop" into the lid. It's dangerous, and like your mom probably warned you, you can cut yourself. Shooting the can will prove to be messy and will probably empty the can everywhere. Not recommended, either.

But I learned a new and safe technique for opening tin cans today, and I thought I'd repeat it for those of you who may be caught without the means to open a normal tin food can.

First, find a flat and even rough surface - a sidewalk will work, as will a tough rock with a surface on it that will accept the can being placed evenly on it, top down.

Some cans have a rounded bottom, and the other "top" side will have a lip around it - that's usually the side with expiration date on it. Some cans are lipped top and bottom. Pick the one or either of the two if there are two lips. Place the "lipped" side down on the rough flat surface. Recognize that the "lip" is actually a seal - the lid is a separate part underneath it.

Holding the can down evenly on the surface, start scraping it on the flat surface, back and forth, or if you prefer, rotating it. Use lots of downward pressure. What you will do is grind off the whole seal evenly. Don't just try to scrape off an edge. When you see liquid coming out of the can, stop. The seal has been broken. Use a knife, a key or similar slim object, slip it under the lid, and pry it off.

Done. Enjoy whatever's in the can.

Thought you might find this trick handy some day.

I just use my bare hands to rip the lid right off the can. ;)

I have actually used a knife to cut open cans if I did not have a multi-tool with me. It was not hard, and what's the use of having 75 or 80 knives if you cannot abuse them occasionally.

I was in a rural part of Spain (Alburquerque in Extremadura) a couple of years ago, and purchased some canned goods at the local tienda. There was no abrelattas (can opener) in the apartment I was renting. The tienda didn't have one, the "Chine" store (store selling cheap Chinese goods) didn't have one, but I finally found one for 1 Euro at the Ferrateria (hardware store) that was similar to a P38, but much larger. I had walked all over town looking for one.

That evening I used my abrelattas, and as I tipped the contents of the can into a saucepan I noticed that it had a pop top, on the BOTTOM!

Looking at all the other cans I discovered the same thing. No wonder the locals thought that the visiting gringo was nuts.
 
Interesting method. But, I never go anywhere except on an airplane without a good pocket knife. In the event of a plane wreck that I survive. There will be plenty of metal avalible and probably not many cans of food.
 
I learned that trick in Mozambique in Africa in the late 70s when I was traveling there often on business. It has the advantage of leaving the top rim quite smooth, the Africans would then keep and re-utilize the empty can as a drinking "glass". This was way out in the country, the people there were dirt poor. Cans of food were from comodities donations from USA or European countries.

Los tiendas no vende navajas suizas? :eek: :confused:

(I hope I just asked if none of those stores sold Swiss Army knives. Or Spanish copies, which can be pretty good. Aitor is one brand.)

I'm half lost without a Swiss Army knife, but used to carry a P-38 in a rubber coin squeezee. It tore the leather when carried in a wallet pocket.

Corkscrews in SAK's work, but larger ones work much better. I like the wooden ones with two handles.

I use an electric can opener at home.

Close: ¿Las tiendas no vendían navajas suizas? Tienda is feminine, need a leading inverted question mark, and proper verb form.

You know, I didn't even think about that, I was so focused on the can opener that I didn't think about implements that might contain one.
