Have you heard about shredding scissors? The container store sells these multiple blade scissors as an alternative to shredders. These are space and energy efficient if you do not have a shredder.In my business I see many shredders that can't handle the typical paper flow in a clients home. For $8.99 it is a great stocking stuffer.
