With a saw file, practice and a little instruction you can take any saw and turn it into a gem. This is the entire range of saw files for sharpening any kind of Western saw. You should always use any file with a handle, sold separately. Our files are made in Switzerland by Grobet.
Note: Saw file have different tangs than regular files and therefore do not correspond with the usual handle size recommendations. Nearly all of our saw files use a #3 Skroo-zon handle (see below for the link). the 4" double-extra slim uses a #2, and the 7" slim uses a #4. The Swiss needle files doesn't not have a Skroo-zon compatible tang.
