nice idea for those who can wear things on their wrists. I have a couple of those magnetic parts dishes stuck around in places like on the dash of my backhoe and the cowl of my 8n tractor seems the best place for me to leave them. Had 1 on a work bench for a while but it collected stuff worst than a flat surface so it now hangs on the side of a tool box for those times when I'm working on a truck or piece of equipment then I grab it and stick it to a bumper or the frame or something.
