@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 ...
