Shutterbug,
I also use the FD-SR #3 blades for fret work.I do not know if its
the blades or my using a backer board on everything I cut. My backer
boards are old drawer bottoms, paneling, scrap ply wood etc. Do not
have tear out problems, at least so far that is. Most times the backers
can be used,like when your cutting christmas ornaments.
