Abstract
A paper shredder with a cutting mechanism and strippers that are formed on the bottom base of the shredder. The strippers have an arcuate shaped portion to substantially surround the space between adjacent cutting disks to prevent shredded paper from accumulating and clogging the cutting mechanism. The paper shredder has cutting disks with teeth that include a piercing tooth and a flat tooth.
