sandpaper is an even more bad idea
ive tried sandpaper before and it just ripped the wires apart. no matter how lightly or how fine the sandpaper was
the teeth idea, as bad as is sounds worked tons of times where i was too lazy to use wire cutters or burn off the plastic rubber.
I'd have to disagree with you on this one. It may have worked for you, but using your teeth as a tool can cause far too many issues than its worth. Very slowly using sandpaper
will most definitely do the trick. Your teeth don't have very much precision, and although sandpaper doesn't either, using it carefully will get the job done.
Of course the best path would be to use wire strippers, however, op doesn't have any. He also said that there was some weird coating that wasn't rubber, leading me to believe sandpaper would be the prime tool to use slowly and carefully, in hopes of removing the coating
