It's tempting to purchase a set of magnetic screwdrivers, isn't it? There are occasions where being able to lift up a dropped screw, nut or c-clip with a magnetized screwdriver just makes sense, but don't invest in one. The reason? Because most of the time a magnetized screwdriver will move a fastener around or otherwise make itself a nuisance.
Instead, keep a refrigerator magnet — or other suitable magnet — stuck to your tool box. When you need a magnetized screwdriver, just wipe the tool in one direction only a few times across the magnet. Voila, it's magnetized! When you want to demagnetize it, wipe the tool across the magnet in both directions.
