I've been dutifully trying to sharpen my chains with an Oregon file (made in Switzerland). Unfortunately, I couldn't tell that the chain was any sharper. After reading a bunch of posts on here, I tried something different.
First, I went out and bought a couple of new files (same brand, just new). Second, I was scrupulous about only filing in one direction with the file...in my case, I tried pushing the file for three strokes on each tooth.
Voila! ShaZaaam! I could feel the file really biting into the chain! Best of all, the chain cut great!
I realize that I had been using a worn out file that I had been pulling/pushing back and forth, rather than in just one direction. Hope these hints help someone else to touch up their chains at each new tank of gas.
