A waste material shredder having a pair of counter-rotating cutter rollers with mutually meshing cutter disks mounted thereon, and fixed spacer members separating the cutter disks. Sheets of waste material are shredded into small chips by the action of sharp protruding teeth on the cutter disks which punch transverse slits and by subsequent shearing action between adjacent opposing cutter disks. Jamming of the shredder due to build-up of chips between the spacers is eliminated by a special configuration of the cutter disks, with chip clearance protrusions being formed between the teeth which act to completely remove the cut chips from the shredder, thereby overcoming a basic problem with prior art "cross-cut" type shredders.
