A bale processing machine features blades that gradually increase in width toward their cutting edges. The blades are mounted on a rotating drum by pivot pins passing through eye portions of the blades. By gradually increasi ng the width of the blade portion extending outward from the eye portion, the effective cutting area is increased without the significant increase in mass associate d with widening a typical blade of uniform width. Furthermore, this gradual widenin g concentrates mass at the blade tip to better distribute kinetic energy at th e cutting edge of the blade during drum rotation. In a second embodiment, the blade is twisted along the blade portion to set the cutting edge at an angle to impro ve cutting performance in the case where the drum and the strands of baled material are parallel by ensuring the cutting edge extends across the strands.
