ABSTRACT:
A slicer blade for cylindrical potato strips includes a plate member having a plurality of closely spaced cylindrical holes formed therein. The edge of each hole is beveled, as by a countersinking-type bit, preferably with the beveling tool being inserted into each hole the same distance, so that the surface of the bevel at least reaches the center point of the triangular space between each cluster of three holes. The previously flat triangular space thus is transformed into a three-sided sharp pointed peak. Additionally, the beveling creates an edge between the holes which also becomes sharpened to the same slope or angle as the peak. The edge between each pair of adjcent holes is formed into a concave shape which curves upward to the sharp-pointed peak. The combination of closely positioned holes and the beveling of each hole produces a sharp cutting edge about the perimeter of each hole without leaving any surface of the slicer blade which is transverse to the flow of the potato. A preferred arrangement of slicer holes is hexagonal, but is not so limited.
