ABSTRACT:
A shredder for shredding data bearing substrates has a housing and shredder mechanism with cutter elements for shredding paper. The cutter elements are positioned along two shafts and interleave with the other when rotated relative to each other. At least one of the cutter elements comprises a pair of outer blades, preferably made of metal, and an inner support, preferably made of a plastic. The outer blades and inner support are aligned circumferentially to form a cross-cut tooth. The outer blades and inner support may be designed such that they are snap-fit together. The outer blades may be formed from a stamping or punching process, and the inner support may be molded.
