I have a set of paragon brass backed handsaws (dovetail and Tenon) whose teeth came filed with a knife edge on each indiviual tooth, as though a file had been held angled at 45 degrees inclination dwhen filing it. There is too much set on the saw and it never cut very well, especially the tenon saw. Would it be best to refile all the teeth wtih the file at 90 degrees so the knife edge on each tooth is squared off, or file it with the same knife edge. I was planning to hammer out the set and re-set it with less. Thanks for the advice. It should be in a rip pattern, but I think it is closer to a crosscut pattern with you each tooth symmetrical Like an equialateral triangle) Thanks.
