By far my favorite tool is the wire strippers. I get so upset watching people use the linesman or diagonals for stripping wire. I believe that the strippers do a faster job ,without knicking, even though you need the extra tool. It also takes LESS effort. Everyone who uses stranded THHN should know. And finally don't leave the house without an induction tester. Absolutely invaluable and saved my hide on mire then a few occasions.(I respect electricity too much and have seen people get hurt first hand.
