When I was about 9 years old, my family moved houses but before we could move into our new house we had to do a lot of renovating. So much so that we had to re-wire much of the house. It was then that I was first introduced to a tool called a wire stripper. The purpose of a wire stripper is to strip the outer coating of an end of a wire to connect it to others wires or to the source of current or so something can use the current. Without stripping the end of the wire, the wire is unable to transfer current. It’s useless. Unless you get down to the wire, the wire cannot be used for what it was designed for.
