The Leatherman Tread bracelet—also available as a watch strap—is intentionally covert. Designed by a Leatherman president after being denied entry to Disneyland with his plier-tool combo, this may be the only tool that can make it through airport security. And it still has most of the utility of traditional models. When you’re ready to use one of its 25 tools, including a screwdriver and a bottle opener, just slide it off your wrist and fold the band to expose the tool you need. Works like a charm and won’t get you detained.
