I can't disagree with that at all. I have one on my key ring.
Called the 'John Wayne' in the Marines. I, too, still have one on my key ring. The first one I picked up in 1975, it's almost spread flat.
A similar device in the Australian Defence Force (that I first met back in 1970) is called a FRED: It has a spoon on the end, and the official title is 'Field Ration Eating Device'. The unofficial nomenclature is Fucking Ridiculous Eating Device.
