This year, Amazon Santa dropped a Gardner Bender SE-94 automatic wire stripper in my stocking. The SE-94’s jaws automatically adjust to strip 10 to 26 gauge wire. One set of jaws grips and cuts the wire while the other set pulls back the insulation — all with one squeeze. I’ve enjoyed it so much, I spent the last 36 hours looking for wire to strip.
Garnder Bender also included an integrated blade-and-anvil type wirecutter as well as a set of crimpers. If you want a really nice, super useful tool, cash in those gift cards and get yourself one of these for about $14.
