The Pocket Driver Stash Tool, designed by Joe Wu, is a compact tool that's great for kits, bags, and pockets. It holds up to four bits, and ships with T6, T8, flat head 0.6 x 4.5, Philip PH1. It's made of strong and lightweight aluminum. To make use of the driver, simply pop off the key ring and pocket clip (it takes some muscle, be persistent) to expose the hex bit socket.
