A shredding apparatus includes a frame and shafts driven to rotate about shaft axes. A plurality of cutter plates are mounted for rotation with the shafts and are arranged in radial overlapping fashion. The cutter plates may each include cutter tooth groups spaced about an outer plate parameter. A succession of cutting relief surfaces are disposed between successive cutter tooth groups. The cutter tooth groups may be disposed at least partially outward of associated relief surfaces in a radial direction with respect to the drive shaft axis.
