American pattern round file for sharpening chainsaw cutter teeth. The knurled cut removes material more aggressively than a plain cut, and the enhanced tooth design leaves a precise, clean edge on the blade after sharpening. Match the file diameter to the size your saw manufacturer specifies, tighten the chain so the cutters are firmly supported, then file from the inside to the outside of each cutter with the file held against the beveled cutting surface at 20 to 45 degrees to the saw. Sharpen all left-hand cutters from one side of the chain, then the right-hand cutters from the other side.
