Abstract
A document shredder having a rotary cutter with axially extending rows of teeth, each row having alternating teeth of different heights. The heights of the teeth are selected such that the difference in the heights of the teeth is greater than the height of the smaller teeth. This relationship ensures breaking up of the document into small shreds and allows the cutter to be driven at low speeds, thereby reducing the power requirements and the noise level.
