We all carry one or more keys with us everywhere we go. It makes sense to carry a multi-functional tool with your keys to help you get more things done. The Quickey happens to be a neat little product that can open your bottles, file your nails, unscrew screws, pop tags, clip coupons, and open boxes. The design is very small and lightweight, so you can carry your tool with your keys.
The product is on Indiegogo right now. You can certainly survive without one but can get things done easier with it.
