@freemo many years ago, when I was doing repairs, we sometimes had to add wire jumpers onto boards (back in the day when a lot of glue logic was used and that was a way to fix bugs). For this we had to use teflon coated ~28AWG stranded wire and used this tool for stripping https://www.weller-tools.com/eu/gb/precision-tools/products/tweezers/29w30. You would put the wire in the jaws and spin the tweezers around until it pierced the insulation then pulled. I would not use this tool for anything else though ...
@cwh050 I know right... with these ifyou use them right you wont pull off strands... however if you dont you will.
Most people clamp down and pull, that will take wires. If you clamp down, then let go and pull the insulation off with your hand it wont take wires.
