My husband is a mechanic...and gets all kinds of discounts on weird stuff like the magent bowl for nuts and bolts. I've just asked him to pick me up one the other day...he kept reminding me that they will magnetize my pins over time.
Of the stuff he's gotten me from the tool department I do love love love the magnetic reachey thing. Apparently if they drop a bolt or something around the engine this thing is really long and will grab it for them. I love it to pick up stray pins that always wind up in places I can't reach.
