I've been working on the power in my basement (adding a couple of
circuits and lights for the shop) and have been using a new wire
stripper. The thing is really slick for stripping NM cable and
working inside boxes. I've had some others that work OK, until
they're dropped or are used to try to bend wire. Once they get
whacked, they're never the same. These are strong enough that that
doesn't happen. Nice!
