Biru / cranked wrench key holder


Most of the holders of cranked wrench keys are not designed at all and very inconvenient to handle with.
“Biru“ is different. On the one hand, “Biru“ keeps the wrench keys and sorts them by size. On the other hand, it presents the keys and is handled easily and intuitively.
The design of “Biru“ is minimalistic. Its round and curved shape contrasts with the straight and edged forms of the world of tools. The design benefits as well as the function from the fact that there is no unnecessary material.
My concept consists of a stamped piece of spring steel being overmoulded with an elastomer.
