I am using these Olson Mach speed univ no. 3R blades 13 tpi 7 skip for 1/4 pine plywood and so far it seems to be doing a good job but what the heck do I know? Also why does some saws have like a fence that holds the wood down and some dont? I have the newer skil variable speed saw that has a shield that holds the wood in place to keep things from jumping everywhere.
