You've jogged my memory we had to make a stripping bar at college. The ringing tool, I' sure I've still got one. Must be worth at least £500I was taught the cutters method or to use a stripping bar (old screwdriver with a slot cut in it)
I've now got a joistripper, but it only does certain sizes, so the manual method still has its uses.
The tool to get the clean cut is a ringing tool, I've lost mine which has really annoyed me so I have to make the ring with a pair of cable shears at the moment
