How Paper Shredders Work
The paper shredder itself usually consists of a receptacle or bin where the shredded bits of material land. The top of the bin is fitted with a lid where the paper is fed into a slot. Strip-cut shredders may use rotating knives to cut the paper, while cross-cut shredders may use two sets of teeth that rotate in opposite directions to get a much smaller, square particle [source: Dahle Shredder ].
