Israeli-based designer Yaacov Goldberg might have created the perfect accessory for all of your spy fantasies. This multifunctional tool and hair barrette was initially designed to be a kippah clip to fasten yarmulkes to one's hair, but it appears to have a secular use as well. The chrome Leatherdo features seven tools in one. That's not even counting its original purpose—y'know, holding your hair back.
Each of the clip's parts functions as a potentially life-saving tool when disaster strikes. There are three screwdrivers (large, small, and a Phillips), a four-centimeter ruler, a serrated edge for cutting, a finish that functions as an 8mm (5/16) hex wrench, and a trolley coin tool.
And while it may not be able to function in heavy-duty situations, we can think of plenty of situations where a miniature toolbox on the go might be handy: tightening a screw on your eyeglasses, peeling oranges, cutting rope, etc.
