Review on PFERD 17038 Classic Diameter Length: Superior Quality, Unmatched Performance by Mood Neboet

I like to leave my files on the truck so my less experienced workers can sharpen quickly. They were well packaged and in perfect condition. I used one file for about 7-8 chains and they still cut great. Keep them sharp longer and make sure your chain is clean. I use a wire brush and some compressed air to remove dust and dirt before sharpening. Don't press too hard, let the file do all the work.
