AndrewB, when I cut out my forms I used a new high quality blade made by Bosh. My saw takes the T-Shank blades so the part number is T101BR. These blades look like they have two rows of teeth and are designated "10TPI DPP D/PO. I had no splintering, in fact the cut surface looks like it has already been sanded. When using regular blades, even new, there was no splintering but the surface was no where near as smooth.
Good luck,
George
