All things considered, and assuming that, like it or not, I'd need a knife I could take everywhere (but an airplane or a courthouse I suppose), then I would probably opt for my current EDC, a Victorinox Super Tinker. If I were lost in the woods I couldn't baton with it but how likely am I to get lost in the woods.
Super Tinker it is...two blades, scissors, punch, 3 screwdrivers, can opener, bottle opener, tweezer, toothpick, and that funny little hook thing I go no idea about...and still in a tool called a knife.
