Exposed Wire

Well I have some Karma Kable that I was cutting today for my subs. After cutting the outside jacket off a certain piece, I noticed that I had cut too deep in some places. There are a few spots where the blade went through the outer jacket and inner jacket of the wire, and the wire is exposed. Will this hurt anything, should I scrap this piece and use a different piece? I think if the wire is showing its no good, but my friend that is helping me install it wasnt sure and said it might not be a problem.
