Gang,
I have tried to sharpen with a hand file, a Granberg and failed miserably with both. I had a dremel kit lying around and used it yesterday. Holy forking shirt, my little 50cc Jonsered went through 28-inch trees like poop through a goose. I guess it's all a matter of expertise...some guys can get a chain razor-sharp with a hand file, but not me
