Abstract:
1. A sawing blade comprising flat parallel sides and peripheral forward-positioned teeth as cutting elements that project laterally beyond the plane of the sides of the blade, wherein the improvement being distinct disconnected tiers, spaced apart from one another of finishing elements projecting from both sides of the blade having flat working surfaces all rubbing incrementally tier by tier against the entire kerf as the sawing action of the blade thrusts them through, and wherein each tier consist of a plurality of separately spaced finishing elements and disjoins the material addressed, with said tiers being distinct from the peripheral forward positioned cutting elements, with said tiers parallel to and stepping back from the plane of the continuum of the peripheral forward positioned cutting elements, with said tiers in their receding progression from the peripheral forward positioned cutting elements projecting laterally from the center plane of the saw blade slightly further than any previous lateral projection in tier by tier increments, with said finishing elements having similarly textured working surfaces on any individual tier, with said tiers having dissimilar working surfaces relative to each other, with said tiers in their receding progression from the peripheral forward positioned cutting elements having working surfaces of coarse abrasive on the first tier and progressing tier by tier to surfaces of fine abrasive and to surfaces that are smooth, with said tiers, each in turn bearing against the entire kerf on its side of the blade, performing a distinct step in a collective finishing process, whereby a cutting process using said sawing blade renders both newly cut surfaces with flat, abraded and burnished planes parallel to each other.
