[Harv72b]

I had a swiss army knife that I carried with me in the field when I was in the army. Among other things, I used...

-The large blade to open MRE packets, spread MRE cheese on MRE cracker (when the temperature was between about 50 & 74 degrees F), and occassionally cut things.
-The toothpick to clean the gunk out from under my fingernails.
-The small blade to cut smaller things or to spread MRE cheese on MRE cracker when the big blade was too dirty.
-The file to whittle away at the edges of the countertop in our command track, when bored or otherwise destructive.

Actually, that was pretty much it.
