Many multipurpose pocket knives are a bit on the bulky side. My pockets are full of enough stuff as it is, so the thin Tool Logic Survival Card appeals to me. Despite its thin profile, it sports a fair-sized stainless steel blade, tweezers, a toothpick, a magnifying glass, a compass, and a bit which acts both as a bottle opener and a flathead screwdriver. The whole Survival Card weighs a mere 1.3 ounces. Not bad for something under $16.
