I have collaborated with Torsten Conradi, a spring craftsman at Jurgen Perleberg in Berlin and designed an almighty clip hanger. It can be clipped on to 3-5cm thickness horizontal surface allowing to hang anything under 10kg.
It could also be hooked to a pole when hanged the other way round. With its variety of usage, it can be used in workspaces at offices and schools as well as kitchens.
