An improved abrasive tool plate for surface smoothing of wood, plastic and other soft materials comprises a thin steel plate (10), 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 (11). According to the invention, the tool plate (10) is thereafter rolled in multiple steps between one rigid roller with raised parallel strips and one elastically deformable roller to deform the plate (10) so that the etched side shows parallel ridges (13, 14). Preferably, the ridges (13, 14) are formed in two different directions, so that they form a rhombic pattern. |
