I've heard of using a drill press to make sure the driver tip doesn't slip, but if the blade on the driver bends, because it has to be so thin, I'm not sure that would help. Those Germans didn't mean for their guns to be worked on and cleaned, I guess. Mine needs neither, but I can't stand having a gun I cant take apart myself, if needed. Guess maybe I'm meant to be a bolt gun man. Anyone interested in a nice Merkel?
