I have been using a Husqvarna 36 for a few years, and I have always used Husqvarna's file to sharpen the chain in the field. I also have a Husqvarna file for my 455 Rancher. I am able to keep the chains sharp for a while, but eventually it seems like the files get less effective in keeping the chains sharpened. What do you guys use to keep your chains at maximum sharpness? Any special files or jigs? Where do you purchase them? Any suggestions on sharpening would be welcomed. Thanks a lot!
