RingTool: A Circular Multi-Tool Keyring

The RingTool is a circular compact tool-kit that you can connect right to your key ring to have an array of tools right at your fingertips at all times. Originally designed for bicyclists to carry around to fix their bikes in an emergency, the RingTool's uses apply far beyond just bikes as it has a ton of different features built right in, such as a 3mm, 4mm, 5mm, 6mm, and 8mm hexhead, a flat-head screwdriver, a phillips screwdriver, a Torxhead T25 driver, spoke wrenches for both .130" and .136" nipples, can be used as an emergency drill bit (see the video below), and even opens bottles using the inside ring of the device. The RingTool comes in silver as the default color, but you can get matte black or gold finishes to choose from for a little extra cash.

The RingTool is TSA approved so feel free to threaten your flight attendants freely with it without worrying about being labeled a terrorist, and comes with a lifetime warranty. Check out the RingTool multi-tool in action via the videos below.
