[QUOTE="Steve White, post: 213651, member: 12457"] ^^^ I gave up on wrenches with knockout cutters some time ago. The first evolution from wrenches was to a 1" socket in a 1/2" drive ratchet. That works pretty good on electrical panels out in the field - I was an electrician back then. Socket/ratchet is always ready to go in toolbox - no batteries to keep charged.
