A hand-held guide for use in combination with a file for sharpening chain saw cutting teeth, the guide holding said file in axial compression to permit mounting of said file at the axial extremes thereof and to facilitate rotation of said file relative said guide during use. A portion of said guide is designed, when said file is axially compressed in said guide, to abut the cylindrical wall of said file throughout a substantial portion of the file's length, and this same portion is formed as a guide designed to accurately locate the file relative a chain saw cutting tooth, and to provide a gage for determining the proper height of the depth gage portion of chain saw teeth.
