I've been messing with the stuff, again. I think I'm doing OK so far, but have a few questions. I started a discussion at the Forestry Forum, and got a few views on my technique, but I'm still in the dark. What else is new, right? I've been filing from the same direction as round filing, but about ten years ago when I got my first loop, the dealer told me to file into the point of the chain, not from behind. At first I didn't get the corner perfectly square, but I seem to be getting it consistently now. Any advice from you guys who use it all the time would be appreciated. Thanks.
