I honestly don't know why I wasted so much time stripping cables with other tools when something like this exists.
Check out the little video to see just how easy this makes stripping wires ready for soldering, joining or putting in to junction boxes.
This tools will strip any wire from 0.2-6mm just using 1 hand (well 2 I guess as you need to hold the wire too!).
You can strip up to 25mm off the nd of the wire which is more than enough for most jobs on the layout.
Wire sizes: 0.2-6mm
Strip max length: 25mm
