Agree with several posts here; however, for me, it is a pair of screwdrivers I paid less than $5 for at Harbor Freight. What makes these special is they are about 2 feet long. If you work on EM's, you will immediately appreciate them. Removing stuff in the front of the backbox or in the bowels of the cabinet are a breeze since you can snake them through the maze of wires and parts. And since the are so long you can do so at an angle that allows enough contact with the screw head. Finally, since the handle is so far removed from everything, you can always get a full grip on the handle and bear down if needed. You don't have to remove the wire clips and other parts to get to right what you need or contort your arm/hand in weird ways.

This looks to be the new and improved version of mine: https://www.harborfreight.com/2-piece-super-long-screwdriver-set-34253.html
