Just a warning guys. I bought a pair of regular wire strippers at Home Depot just to have an extra pair around the house. Didn't realize "Commercial Electric" was their house brand, and anything but commercial. Used them for the first time yesterday. Cut a 12awg Romex cable with them, and the cutting edge deformed so badly that they wouldn't close. Filed it down and then was breaking plaster ears off a receptacle and the jaws went over-center somehow. I called HD customer service to let them know they shouldn't be selling garbage like that, but I doubt it will do any good.
