A fold-up style housing contains four hex keys (3mm, 4mm, 5mm, and 6mm), slotted and Phillips screwdrivers, a 1/4"" socket driver with 8mm, 10mm and 12mm sockets, 13mm and 14mm open-end wrenches, and three spoke wrenches (6.0, 6.3, and 6.4mm). With the exception of the three sockets, all pieces are permanently attached. When any given tool is being used, the others can be folded into the housing, which can be used as a handle over a range of angles. All tools are heat-treated chrome vanadium or carbon steel, and manufactured to precision tolerances. The unit measures only 3.5"" long, and weighs a mere nine ounces.
