I think this Handy Manual Shredder from Poketo is what I need at the office. Not only would it help to shred important documents and what-have-yous, I can get a little workout while doing it too. Why? Well you need to crank this shredder manually by turning the the handle. No electricity is required. The retractable handle hides neatly on the side and this make storage easier on the shelf or display on the table.
