When winding toroids by hand without a toroid-winder or
its fancy winding bobbin, there's lots of flexure on the
ends of the fine copper wire from all the threading-through
the hole. Copper is maleable, but there are metal-fatigue
limits even with copper. Using something that scars the
surface, plus the metal-fatigue phenomenon from dozens of
threading movements, makes it easy to damage the ends.

Yes, I've tried fine steel wool in removing enamel from #32
and it is as inferior as perpendicular knife-edge scraping.
Such works okay on #26 or larger where one can afford to
lose some copper in the process.

You can predict wire length well enough to strip it before you wind the coil? Wow. I always have to wind the coil, cut off the 0 to 4 inch miscalculation (I always shade it high), then strip.
