Original purpose: Securing papers.
Aha! use: A clip-on key chain/money holder that's ideal for your morning walk. Take a 1¼-inch binder clip and pinch one of the wire arms toward the center to release it from its hinge. Slide on your key and refasten. Clamp to your waistband with a few bucks for coffee and a paper.
Reward: No more wondering where to stash your key and cash.
