Most people use their teeth or nails to strip wires, I can't do either. I have always had a hard time stripping cables and it is not something I can do cleanly in one attempt, especially with poor quality cables where the wire is much weaker than the insulated coating. A few years ago I saw my motorcycle mechanic using scissors to strip wires quite effortlessly. I tried it and it works best with blunt scissors so this was not so effective for me either. Yesterday I had to connect a few cables and before I started, I bought these wire strippers. I have seen electricians using these all the time but never thought about getting these for myself till now. I guess this is what they mean when they say "The only thing stopping you is yourself"
