This Key Chain Magnetiser/Demagnetiser from Klein uses permanent rare earth magnets to magnetise or de magnetise your screwdrivers, screws or driver bits so you never drop a screw again! (you probably will but this will help)

With a stainless steel keyring this little accessory is handy enough to attach to the zipper of your tool pouches or bags.
