The Field Ration Eating Device, or “FRED” for short.

Five FREDs 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.
