He sharpens the back of a razor knife. He draws it along the Plexiglas two or three times (somewhat like you would glass) and then he snaps it just like glass. Then he takes a file and runs it over it a few times to make sure that it is smooth. He found a scroll saw had a tendency to melt the Plexiglas if you run it too fast. If you have a variable speed scroll saw it would work well on a slower speed. I have never had a problem with any of them he has made for me.
