"Not to mention the window-smashing attachment" That can be handy when trying to rescue someone, or so my volunteer firefighter friends tell me. Claiming that such a feature has no legitimate purpose is like claiming that a crowbar has no legitimate purpose. "I fail to see the non-weapon use for a knife that is small (and therefore concealable) and also opens quickly" Small knives are easy to carry around, that should be obvious. As for opening quickly, that is just a convenience -- why should convenience be frowned upon? Would you be less concerned if these were fixed blade knives? Sure, knives and crowbars are weapons when you apply them to human beings. People have been murdered with screwdrivers (is a small screwdriver a bad thing?). On the other hand, the NATO e-tool, designed for use by soldiers at war, is often used for gardening because it is convenient -- it can be used as an ax, it can be used as a shovel, it folds up for easy storage, etc.
