I am not an electrician, but when we had one come out to do some work ( and a great job at that! ), I was fascinated by the "crank" screwdriver by Klein. It had an offset shaft that rotated in the handle. This tool is the ideal alternative to a normal screwdriver and a power screwdriver/drill. A regular screwdriver just gets tiresome after a while, while a powerscrewdriver/drill can strip out the hole ( not to mention running out of juice when you are ALMOST finished ). It makes short work of installing or removing switches and outlets and covers. I went out the next day and bought two ( phillips and blade ).
