Indeed, but why buy one for what may be just a few hundred CDs?

- Paper can be simply burnt in an old metal can.
- CDs can be fractured in a few minutes. Get a stack, put one on a
piece of plywood, whack a brick bolster with a club hammer twice
radially, place it in bin, get the next one, repeat.

Shredders are sort of like electric bread knifes.
