In 2016, the Tactica Talon became the highest funded multitool in crowdfunding history. Using the feedback from thousands of backers, it's since been improved and rechristened the Tactica Original. Packed into its 3.1-inch case that can be attached to a key ring are a multitude of tools, including more than a dozen wrenches (imperial and metric), a bottle opener, a package opener, a ruler, hex sockets, and both Phillips and flathead bits. It's TSA compliant, so you can leave it in your pocket while flying, and its hardened steel core is wrapped in a lightweight composite that won't scratch your phone's screen.
