Sharpening the 3/8ths full chisel chain on my Craftsman 3.7. I don't know who makes the chain but I doesn't have mark to indicate the angle. So I defaulted to 30 degrees. About half way through the first side, I started wondering why my file was so far off the angle that existed on the dull cutters. Duh, the original angle is probably 25. Sure seems like what my angle guide says. Next sharpening I get to fix that.
