Sash, the guys have pretty well covered it. If you haven't done any draw filing look at Don Fogg's site, it covers it pretty well if I recall correctly. One tip that might help or maybe two is 1. use a new file, it cuts sooo much better 2. keep your file clean, chips will leave some gouges you would,t believe 3. lay your blade on a flat surface to file, if you don,t the blade flex will cause you to chase your lines back and forth. Well that was three, but Okies can't count anyway. Hang in there. :0) mike
