This is a method of stripping wire that one of my friends showed me. I noticed that I use wire for a lot of projects and don't have a wire stripper. This way is useful if you don't have a wire stripper and you're either broke or too lazy to get one. It may seem like it takes a while to do, but once you get used to it it barely takes any time at all. This method is similar to the one by Weissensteinburg, but my friend said that this way may be better for the wire (less likely to damage it) but I'm not sure. Feedback is always appreciated! Remember, If you liked it you could always rate it +1 :)
