ABSTRACT:
A corrugated knife fixture is provided for cutting vegetable products or the like particularly such as potatoes, wherein the knife fixture includes one or more knife blades each having a cutting edge with a variable pitch and variable amplitude geometry. The knife fixture is particularly adapted for cutting whole potatoes into a plurality of wedge-shaped pieces each including a pair of wave-shaped cut surfaces which angularly intersect at a narrow cut tip located generally at a longitudinal centerline of the potato and diverge radially outwardly to an enlarged heel corresponding with the external surface of the potato which may remain unpeeled. The knife fixture, and the resultant wave-shaped cut surfaces of the potato wedges, is defined by the variable pitch and variable amplitude cutting edge wherein the pitch and amplitude increases from the cut tip of the wedge toward the heel or external surface thereof.
