Spectrum Supply seems to be the only once for the "Lenox KERFMaster." The www.lenoxsaw.com page seems to say nothing about a blade stock called KERFMaster. The specs of the KERFMaster stocks seem to be identical to the stocks the WoodSlicer/Blade Runner are available in.
Has anyone confirmed these blades are made from Lenox stock? Any other suppliers than Spectrum? Has anyone compared them to a WoodSlicer or Blade Runner?
