A material shredder including an elongate rotor including distributed, outwardly projecting cutting teeth having cutting edges collectively defining a rotor cutting profile, and an elongate bed-knife disposed operatively adjacent the rotor and possessing distributed cutting edges collectively defining a bed-knife cutting profile which meshes complementarily with the rotor cutting profile with rotation of the rotor, these two profiles collectively defining an elongate shredding interface wherein there are certain reverse-facing, mutually facing, respective cutting edges in the teeth and bed-knife that face, respectively, toward and away from the rotor.
