Well i had an old hard drive lying around that i dismantled and there is a super powerfull magnet inside, i found that attaching it to the screwdriver makes the whole screwdriver supermagnetic and you wont loose any of the small screws.

Please be careful with those powerful magnets! There is significant DANGER involved.
ALWAYS WEAR A FACE SHIELD, simple eye protection is not enough.
