The solution to starting or extracting screws from tricky places is to magnetise the blade. Simply running the blade through the 'magnetising' slot gives more than enough magnetism to pick up and hold a screw on the tip. To 'switch off' the magnetism or de-magnetise a blade, simply run the blade in and out of the other slot a few times.

Magnetiser/demagnetiserA brilliant gadget. Most people know the trick of magnetising a screwdriver, but the problem is it stays magnetised and will pick up all kinds of ferrous objects. This thing demagnetises as well, so your screwdriver doesn't look like a steel hedgehog. It also greatly impresses young children.
