I can't believe it !! , I picked up a couple 3/16 files and a handle today to give filing a try after maybe 25 years . What I can't believe is how nice the file cut into the cutter , just like butter !! Now this was a real nice chain , all it needed was touched up . I free handed 2 strokes each and went out to the wood pile and found some ash and red oak logs that I had skidded down this past summer , man it cut better than a new chain , it had that good pull into the wood like it should , and I wasn't getting that with my dremel tool . I don't know why I was so against files from my youth except maybe they were all worn out , I can remember struggling with the files and they wouldn't cut ,they would feel like they were just sliding across the cutter and not cutting . Well now I'm looking forward to filing up some real good sharp chains and getting some nice big chips !!!!! Thanks for the input guys !!!!
