A saw blade having one tooth tilting to the left, one tooth tilting to the right, and a third tooth straight, repeated throughout the saw blade. Tilt causes the set teeth to be shorter than the straight teeth which first contact and cut the foam and fiber glass strands. The cut strands are free to move away from the following raker teeth which remove additional foam, leaving the desired tufts.
