When I nicked my cable with a broadhead last month I thought about continuing to use it. 4 strands were cut. I decided it wasn't worth the risk. I ordered a new one from Gibblet, ( it got here really fast!),and put my old factory cable back on. It made me really glad I saved the old one and had purchased a Bowmender press from WWAG.
I guess I shouldn't be playing with sharp things either! Maybe I'll take up rabbit hunting with blunts.
