Encouraged by Buckin' Bill's vids, I resharpened by 25" RSC last night with slightly more gusto than usual.
I noticed that on one or two cutter sides a very tiny bit of burring happens since presumably sometimes the very last piece of metal gets left behind by the file stroke.
What do you peeps do about those burrs? Just leave them right? I don't think that it's the chain saying "Matt you're pushing too hard", cos that Billy Ray was certainly using no less force from what I could see.
