It works great. I have done it dozens of times. You will end up with little fuzzies all over the place.
Already done. I used a standard Freud 10" blade. I can't get too fancy with blades because I have a SawStop saw.This is just a random thought, though maybe a little late 10 days later. John Heisz made a paper saw blade and actually cut some thin pieces of wood with it. I wonder if you could make one out of some cereal box cardboard and use it to cut through the foam little or now snow?
