  • Patent number: 7055515
    Abstract: This invention relates to tiers of kerf engaging elements at saw blade sides. The tiers recede from the blade's most forward peripheral cutting elements and project laterally to engage the kerf in incremental steps as the blade advances into the material addressed. Each tier is designed to perform a distinctive action. Individual tiers may be designed to plane, or shave, or scratch, or scrape, or sand, or burnish. The mentioned preferred embodiment of this invention submits the kerf to coarse sanding, fine sanding, and burnishing with one pass of the blade.

  • Patent number: 6543326
    Abstract: A protrusion on the side of the saw tooth rubs against the newly cut kerf surface as the tooth cuts. Pressure, friction and friction-generated heat are produced through this rubbing action. The confluence of this pressure, friction, and heat, performs a polishing action against the newly cut kerf surface.

  • Publication number: 20020194975
    Abstract: This invention gives saw blades multiple tiers of saw teeth. Each tier of teeth is designed for and dedicated to a particular cutting characteristic. The first tier to engage the material being cut has fast cutting characteristics. Each subsequent tier cuts away the kerf surfaces left by the preceeding tier and cuts a new smoother kerf.
