While I was in the middle of my table saw search I noticed that some of the sliding table saws and high end European saws had a scoring blade. So I am wondering why we don't see more of this and if any of you guys make a scoring cut on plywood and laminated face material before making the actual cut.
It looks like it would be easy to make a pass at a lower blade level to score the surface then make the final pass with the blade at the correct height.
Or is a scoring blade more of a gimmick than something practical.
