I have used many different pairs of wire strippers and these are by far the best i have ever used. with most other wire strippers you need to find the right hole for the right size of wire and sometimes they dont cut through the insulation all the way. With these cutters you just place the wire in the mouth and squeeze the handles and you are done, it pulls the insulation off and you are ready to go. You can set the length gauge so that you get the same length every time that you cut.
here are the strippers i have Kronus Wire Strippers
