the arm portions 11 also include a linear cutting edge 20a 20f which also intersect with the cutting edges of the central body portion at points 19a f with reference to fig2 and 3 it is noted that the inner cylindrical wall portion 21 which defines a cutting element cavity 15 is generally circular in cross section throughout a substantial portion of the height h of the cutting element from the upper surface to the lower cutting edges thereof the lowermost portion 22 of the side walls defining the cavity are tapered outwardly along their length from a point spaced below the center of the height of the cutting element as shown in fig3 to define the cutting edges shown at 18a 18f no more than one half of the height h of the cutting element should be shaped with a tapering wall portion so that when the cutting element is used a substantial portion of the cavity 15 will have the shape of a cylinder or be of circular cross section so as to insure that the product being severed is substantially circular with the only bottom portion of the segmented biscuit or other food product having the straight line configuration which would conform to a hexagon as shown in fig2 of the drawings preferably the lowermost portion 22 of the side wall should be less than one third of the height of the cutting element in a like manner each of the wall portions 13 of the arms 11 has an arcuate upper wall section 13 39 and.
