To then be able to solder to coarser wire.
Assuming coating will not melt off/evaporate at soldering iron temperature
I tend to grip between 2 fingertips and abraid with the finest grade of wet
and dry paper against a fingertip and turning wire around and repeating a
few times. Would abraiding against a block of rubber be better or some other
process altogether ? for minimised chance of localised (so failure point)
weakness due to stretching near the stripping point. Perhaps a small
fine-grade grind stone in a Dremmel with direction of rotation towards the
bulk of wire, turning the wire .
