Every wood saw blade I have seen, has those little groves. There are ususually 4bof them spea dout equally around the blade. What are those for?
The cut outs are also there for saw dust clean out your older blades would get bound up by the saw dust, these clean outs get it moving away from the cutting surface and toward the back of the blade , noise reduction was a happy plus along with heat reduction. For safety reasons they cant remove to much metal but I suppose every penny dose count when your talking profits.

Thanks for setting the record straight on the reasons behind the cutouts. Is the expansion more drastic in the newer materials used? Or is it that the expansion was always there, and the new metals allowed for the cutouts without losing structural integrity?
