ABSTRACT:
A concavely ground knife blade has a pair of side faces characterized by oppositely-directed, continuous, slightly concave surfaces. Such surfaces have an arcuate profile approximately fitting a large (e.g., 30 inch) radius circle and follow essentially straight line axes which gradually bend toward one another to form a point. The side faces are first ground widthwise along a diameter of a grinding wheel having an end face beveled at a shallow angle to form a frustoconical grinding surface. The side faces are then polished lengthwise. The resultant blade has a median thickness in its midportion which is nearer the back of the blade than the cutting edge.
