1. A system comprising:
a radially arranged series of flutes for forming a twelve bladed stalk roll;
six pairs of two flutes, each of the six pairs having:
(1) different total lengths,
(2) a blade defined by a leading end and a trailing end, wherein each trailing end of the six pairs are positioned in relative alignment to one another when formed around a circumferential surface,
(3) an opening formed at the leading end of the blade,
(4) a blade taper with a heel, and
(5) a flute segment that is not perpendicular from the circumferential surface, the flute segment having a (i) back side opposite the blade taper and (ii) a bend;
a linear shredder that causes an implosive contact between another twelve-bladed stalk roll positioned near the twelve-bladed stalk roll and the heel, thereby cutting corn stalks in to segments:
wherein the heel of the blade taper causes a self-sharpening action of the blade that sharpens the blade to an angle of 30° to 45°.
