I have searched for magnetic precision tools for model railroading with no results. The Tool Magnetizer/Demagnetizer has solved this problem. It quickly magnetizes tools so even the smallest screw holds firmly to my screwdrivers and I don't have to search for dropped items. I find it much easier to pick up small items. I am enjoying the magnified tools so much I haven't tried the Demagnetizer yet. I recommend that everyone who works with small items purchase one of these immediately.
