Multipurpose screwdriver, 3 in 1 - flat, hex, crosshead

A key chain screwdriver can easily be modified from a conventional flat screwdriver into a cross-head screwdriver. Can be used as a stylish keyring. Also, mini screwdrivers are very compact, which allows them to fit in any pocket, as well as to be attached to a bunch of keys. The keychain weighs a little more than five grams, so it is easily attached to the keys and does not cause discomfort when worn. The size also allows you to wear it in a jacket or jeans and not be afraid to tear the pocket with the base and break or deform it when walking.
