Abstract: The present invention is directed to a cutting apparatus, which includes an s-shaped blade, for cutting a foodstuff to form a concave, tapered wedge product. The cutting apparatus includes a cylindrical housing member, a ring member, which receives and holds the s-shaped blade, and a base member affixed to the cylindrical housing member. The cylindrical housing receives at least one ring member, typically several. The several ring members, each receiving and holding an s-shaped blade, are stacked together. One or more ring members in the stack can be rotated in order to adjust the angles between the blades. By adjusting the angles between the blades, the size and dimensions of the cut foodstuff can be modified. Typically, the apparatus will be used as part of a high speed processing line.
