This came in today on a 24" Stihl MS660. Talk about stretching the absolute complete life out of the chain, jeez........

That is how far I go. I sharpen until the cutters begin breaking off. On Oregon chain, that point is the witness marks.
Got one with a saw I bought Saturday that had far less meat than that one...
Whoever sharpened that chain knows what they are doing. Look how smooth the cutter bottom is just above the tie strap. The filer keeps a very consistent file depth.
