Swiss+Tech Micro-Plus EX 9-in-1 ($10)
The Micro-Plus EX 9-in-1 is a lightweight stainless-steel keyring that transforms into nine useful tools — and still fits easily in your pocket. It’ll replace the bottle opener you’ve had attached to your keyring since college. And then add not one but four screwdrivers — two standard and two Philips, with large and small versions of each. Pliers? Check. Also wire cutters, strippers, and crimpers. Unfortunately, even with all that firepower, it can’t help when your keys are lost in the couch cushions.
