I'm considering buying the Grobet saw file set from Lee Valley. However I have a 20 pt dovetail saw and I'm not sure I can sharpen it with the smallest file in that set (4" Double Extra Slim). What file should I get to sharpen the 20 pt saw?
BTW - I've never sharpened a saw. I have a pretty good idea how to do it and a couple of saw that are safe to practice on.
