So I bought an Alaskan sharpener jig last spring to see if they were worth the hype. I answered that question the first time I used it and decided that this year I would get the best option which seems to be the Granberg G1012XT. I finally used it the other day and I'm completely pleased. The chain I was sharpening is on a farm saw that gets used on everything from fences to stumps, this chain has been neglected in the worst way. The final result had to remove about 3/16" from the cutters and .020 from the rakers. For a chain that I'd have tossed and bought a new one rather than hand sharpen I was very happy to only spend an hr getting it back in service. I had to do 2 passes on the first side as I found a severely damaged tooth near the end of the loop. The sharpener is a bit of a pain to get setup correctly but it's mainly just taking the time to get everything aligned and set. Once setup its fast and silly easy. The quality of the job is better than anything other than a nice bench mounted sharpener which you can really have with you. For a regular sharpen I think it would be ~15min per saw. Like I said I'm sold, anyone who needs to do any amount to chainsaw work needs one of these.
