I don't know about that particular stripper, but make a trip to the local electrical supply house and describe to them what you're looking for. They'll fix you up with a wire stripper that will make you happy.
Mine's a Klein (don't know the part number off the top of my head). It is spring loaded and automatically measures and strips the wire. I've seen a generic imitation at Harbor Freight for a few bucks that works just as well.
