This quality wire stripper/cutter can be adjusted to perfectly strip any wire sheath, and it's super easy to use! It features a spring to always pop open, and I'll send this to you perfectly preset stripping the jacket off of 28AWG wire, like our Whoop Wire, which is my favorite wire for custom LED jobs.
Just adjust the little stopper to the perfect size and get strippin! Place your wire in the v-notch, close the stripper around the wire sheath, cutting it evenly, then release a little pressure and strip the wire jacket away. You might find a little angle on the wire stripper makes this motion a little easier.
I'll toss in a long piece of 28 gauge wire for you to practice on in case you're new to working with smaller wires :)
