An exceptionally favorable small tool that fits perfectly for a project of mine is by the size, shape and processing, a bike-multitool for "pop-keychain" remodel. The metal housing makes a valued and robust impression, this is not a cheap plastic scrap. Since the stick is very slim and narrow, it can be easily and in addition to other, bulkier connectors use on adjacent USB ports, a problem that is unfortunately too often met me. The only shortcoming (which does not bother me personally): The black lacquer starts to deviate at the corners, who cares, who should perhaps prefer to choose another variation. The result is just quite a nice worn look.
