Yes, it was I who started this thread, thank you, thank you, hold the applause. Anyone who runs a full house chain on a saw with a 28" bar that may see problems, rocks, objects in res. trees, etc. is not the sharpest knife in the drawer, with all due respect. 8-9 minutes to sharpen a rocked out full house 28" chain, even with a new file, properly? And the rakers as well, 9 strokes, musta needed the rakers done too, yeah right. I only change if it rocked out real good, get to clean the bar as well, mostly just do it then and there. Yes it takes just a few minutes to put an edge on my ms200, 16" bar, but it ain't really ever dull to begin with. Sharpened more than a few (dozen, hundreds?) chains all the way to nothing over the years, I don't care who ya are, it takes a little time to do it right.
