First introduced to these back in the late 1980’s. Such a handy little camping tool. It’s a combination spoon, bottle and can opener. Yes, it does take a bit of effort to open a can with one of these things, but it’s better than the alternatives.
ie.
- starving
- using a knife/bayonet to stab the can, or
- using a rock.
I got my FREDs from this ebay seller
