I picked up this saw on the bay pretty cheaply, figured I could use it for sharpening practice. It's a 20" no name saw, it has an etch that is almost invisible and completely unreadable. I spent about 2 hours last night gently coaxing it back into a shape that kinda resembles straight, then went to town with the files. I filed it 10 point per inch rip, and gave it a little set. It cuts better now, still needs some work but I'm pretty happy with my first attempt.
