Circular cutting blade

A circular blade configured for cutting meat when turned about a rotation axis in a predetermined cutting direction, the cutting blade comprising:

• a single overall peripheral blade edge;
• and
• a plurality of circumferentially disposed cutting knives, each of which cutting knives includes (i) mutually convergent first and second knife sides, and (ii) an arcuate knife edge that is defined by the first and second knife sides, constitutes a portion of the peripheral blade edge, and rises, relative to the rotation axis, between a first blade-edge location corresponding to a minor blade radius and a second blade-edge location corresponding to a major blade radius, wherein
• (a) each knife edge is tilted such that an arc-bisecting line that bisects the knife edge at an arc mid-point, and that is oriented orthogonally to a tangent line including the arc mid-point, is non-parallel to a blade-radius line extending from the rotation axis through the arc mid-point;
• (b) the second blade-edge location of each cutting knife is situated, relative to the cutting direction, behind the first blade-edge location of the same cutting knife such that, when the circular blade is rotating and cutting a work piece, the work piece first encounters the first blade-edge location of each cutting knife before encountering the second blade-edge location of that cutting knife;
• (c) the peripheral blade edge further comprises a plurality of back slopes, each back slope is situated, relative to the cutting direction, behind the second blade-edge location of a first cutting knife and in front of the first blade-edge location of a second cutting knife located behind, and adjacent to, the first cutting knife;
• and
• (d) each back slope slopes more steeply than the knife edges between which that back slope is situated.
