Any help appreciated,im trying to tie it to a swivel..
thanks, brian

I would think that any knot which would work with plastic or carbon coated wire should work on the leadcore.

Try the Centauri Knot (do a Google search) - this works great with plastic or carbon coated wire - or what about crimping with the smallest Momoi or Jinkai crimps and a proper crimping tool ("cup to cup" and not the usual and cheap "point to cup" tool type)?

Before you crimp, this article is a "must read": http://www.leadertec.com/tipsandtechniques/crimp_techniques.html

All the best,
