Abstract: A saw blade comprises scratcher teeth which are not set, and shaving teeth which are set. All of the teeth have their leading and trailing lateral edges chamfered. The chamfering of successive teeth occurs at alternate sides of the blade. The scratcher teeth have sharp points, whereas the shaving teeth are truncated to form oblique top surfaces and to render the shaving teeth shorter than the scratcher teeth.

Abstract: An improved abrasive tool plate for surface smoothing of wood, plastic and other soft materials comprises a thin steel plate, on one side of which a pattern of etch fluid resistant material has been applied, followed by etching away the surface between the pattern elements down to a determined depth. Parts of the steel plate protected by the etch fluid resistant material pattern will remain between the etched away parts as protruding elements with flat tops, which can serve as cutting elements. According to the invention, the tool plate is thereafter rolled in multiple steps between one rigid roller with raised parallel strips and on elastically deformable roller to deform the plate so that the etched side shows parallel ridges. Preferably, the ridges are formed in two different directions, so that they form a rhombic pattern.
