The only other engraver I am familiar with who almost exclusively wriggle cuts is Jason Dumars who specializes in brass instruments. If you google him I believe he has a web page and videos on Youtube. He used to be on this forum but I haven't heard from him in some time.
Also there was an Asian engraver that was featured in a thread who used a long wide graver the size of a mill file who had a unique way of wriggling on instruments with it. I believe it was called "flutter" engraving. (KC Steve-Do you remember that one?)
