Bill,
I guess one of my favorites is a cable stripper made by Ideal that strips the outer insulation from circular rubber cable. I worked on a a production line at one time that was having all of the cables to its limit switches renewed, the stripper cut the job in half. It has a guide that holds the cable against an adjustable blade, once the depth is set away you go.

PS what about the worst tool you ever bought.
I have several in mind and they all have one thing in common..........they were cheap.
