I know Teacher, but some of these things have come in handy from time to time. I've had to use the lighter more frequently than I thought, the light and compass,tweezers,gerber,usb drives,keys,nail clipper and lock pick I use actually quite a lot. Really the whistle and the ferro rods I don't really use. And the beauty of carrying all this stuff in your pocket is it makes a great backup boat anchor for a big boat.
