    Wire Stripping with a Knife: If you own a wire stripper, we’re assuming you know how to use it. If not, and you are new to the world of audio construction, you can use a hobby knife to do the same job. Simply cut around the insulation leaving an appropriate length for the lead, be very careful to cut only the insulator and not the wire itself.
