There must be some sort of trick to filing. I seem to dull my round files right away.
Brand new I can feel them cutting away mettal. But after only one or two sharpenings I can feel the file getting "slippery".
I try to sharpen every tank of gas. I sharpen so that the file cuts from the back of the tooth towards the front. And I tap the file on the tailgate after every two or three saw teeth. Still the files seem to go dull rather quickly.
