It's been a few years since I restored an old brush handle with a new boar knot, but lately, I've been enjoying my boar brushes a lot and would like to do a couple of more. What's the best source for good-quality boar knots? I see a few on eBay and I know some people scavenge knots from new brushes (Omega, etc.) I don't mind paying a small premium for a good product. I'm in no rush, so if they ship via a slow boat from China, it's no big deal.
