This elegant Kinetic Driver was designed by Giacomo Di Muro, the YouTube maker and de facto product designer.
It’s produced by Di Muro’s Placed Atoms brand, and they make no bones about the fact that no one needs this tool; the intent was to design something so beautiful and pleasurable to use that it becomes an object of desire.
The key feature of the tool is the kinetic flywheel, shown here in brass:
This has been carefully weighted and rides on a ceramic bearing; giving it a mere spin creates enough momentum that the tool does the driving, or unscrewing, for you.
Upon the tool’s release several years ago, the flywheel was the brass one shown above; in the current version, the flywheel is chromed steel. It’s a pity because the brass really provides visual pop, but I assume shifting supply conditions led to the material change.
The Kinetic Driver runs $120 and comes with the case, as well as 24 bits.
