Years ago I bought this little gadget that I thought would be handy in the shop for magnetizing and demagnetizing screw drivers. It works ok for adding magnetizism to screw drivers but its lousy for removing it. Sometimes I want a driver to hold onto a screw and sometimes it's aggravating. I just recently saw a YouTube tip where the guy just passed the screw driver shank through the energized forks of an electric soldering iron. I just tried it and it works like a dream.
