The only wires that should be in your teeth are braces.
Wire strippers have come a long way since I was a kid. Then again there really was only one reason for me and my friends to ever use a pair. You see back in the day cars didn’t come with cool stereos with speakers everywhere, no, we had an AM radio and one small speaker in the dash. The solution, head down to the local stereo shop and buy a groovy new AM/FM CASSETTE stereo!! If we were lucky, it fit right in place of the old radio. Next, connecting the wires. We usually ran a wire directly to the battery for power. Not a good idea. Now the speakers!! Since we never had a pair of wire strippers, we would use our teeth to strip the wire. By time we were done there was a mass of wires and tape under the dash and we had sore gums from chewing the insulation off the wires.
Avoid sore gums, and get a nice pair of wire strippers! Ideal for example, has a great line. Right now they are offering a limited edition 100-year anniversary wire stripper. It comes in a red, white and blue color scheme to commemorate 100 years of being made in America!
