The best idea would be go now to your local Army\Navy surplus store stock up on a hand full of P-38's
I have to say that we were so interested in this, we took a can of tuna out in the back yard and tried this on the patio. Takes longer on a piece of concrete that has been 'finished' took about 3 minutes of trading off the get it open. But we were stopping and starting a lot just to see what was going one.
We moved to a cinder block and had one open in 30 seconds. I would imagine that using concrete that hasn't been finished would make a difference.
One problem I see here, and we experienced this, flecks of aluminum in the contents of the can. that could be bad. Oh, and the lid is about as razor sharp and jagged as can be. I was using gloves to 'squeeze' open then can, otherwise I'd have had a bloody finger for sure.

I bought a couple of swing-a-ways myself.
I totally agree.
cool! I haven't tried it the only can I had to open was tomatoes and I couldn't risk it LOL
I can't get those things to work for love nor money ... I'd be better off trying to open a can with a smooth pebble ...
I've carries a "John Wayne" (aka P38) on my key ring since I left Nam in 68. BB I can teach you to use one in about 2 mins max.
