I'm about to reach the wire stripping phase of a huge (for me) wiring project. I've had a pair of Gardner Bender auto wire strippers (cheaper SE-94 I think) for a while and they always seemed cool. However, I was testing it tonight and found that on the 12 gauge romex conductors the stripper is marring the insulation on the remaining side a bit where it grips it.
Is this something to worry about? I hate to see the insulation getting marred like that. Perhaps I should be using a more traditional set of strippers, such as a Klein 11055?
