Fly Pry
One of the smallest multi-tools around, the Fly Pry is way more than meets the eye. Made from military grade titanium, it packs loads of functionality into a frame that's the size of a zipper. Use it to open bottles and cans, pry a loose nail, open up a box, or use the 1/4 hex bit for a quick handyman assist. Easy to attach as a zipper pull or to your keychain and available in three models and six different colors.
