Here’s an energy-saving device that’s powered by your own brute force. Imagine – save energy, a little money, and get a mini upper body workout all at the same time, while just sitting at your desk.

Shred your unwanted documents by simply reaching for this hand-cranked paper shredder. The retractable handle tucks in to the side when not in use; the slim silhouette is easy on the eyes and easy to store. A nice alternative to the typically noisy and electric-powered shredder. Comes in grey or turquoise, $45 @ poketo.com.
