OK, I'll admit that I had some time on my hands (dangerous thing, I know)...
I wanted to see how my hand sharpening compared to new out-of-the-box chain. Here is the set-up:
I just received (from Bailey's) 2 boxes of WoodsmanPRO 30RC chain (re-badged Carlton Chain). The saw is a Husqvarna 385XP on a 24" Husqvarna bar. The project was a 20" pine to fall and cut up. I took one of the new chains (at random) and ran it through my typical sharpening process using a Save Edge file and a Carlton File-O-Plate. I ran 2 to 3 strokes per cutter. No need to file the depth gauges here, due to new chain. Then I replaced the hand-filed chain with new out-of-the-box WoodsmanPRO 30RC.
I dropped the tree with my Husqvarna 353 (20" bar) so that the chain on the 385XP would be pristine.
Once the tree was down, I jacked-up the base of the tree to give me room to work without too much fear of grounding the chain. I fired-up the 385 and made 3 cuts. I let my friend run 2 additional cuts. Then I changed to the new out-of-the-box chain with the Jonny Quest hand file tweak.
I first asked my friend to make 2 cuts. Then I made 4 additional cuts. When it was all completed, we both agreed that the new hand sharpened chain cut significantly faster than the new machine ground chain.
What is "significantly faster"? I estimate 10% to 15% faster. Granted, this was not very scientific and really a subjective test. No stopwatches involved, no allowance for trunk diameter as we moved up the tree. The test was seat-of-the-pants at best.
All that said, I will continue to hand file my "new" chain. Also, the Save Edge files are very nice.
