I use wire wrap wire when winding small cores. The Kynar insulation is tough 
and resists nicking.

OT: Wire wrapping was very popular in the 60's and the 70's before the advent 
of multilayer printed circuit boards.

It was very reliable. The backplane of the Apollo Guidance Compluter was 
connected via wire wrap. You can see an example at the Infor Age Museum in 
Wall, NJ.
