The upgraded version MK4 is finally available. 
Beans won't get stucked in the top axis anymore and the glas is a super robust new Ploymerglas that is nearly impossible to break. 

In our eyes, the very best hand grinder on the market. A lifetime investment that pays off from the very first cup. If the particle size is not even, your coffee will never reach it's taste potential no matter how much you work on water quality or brewing technique. The very essential to start making better coffee every day. 

All black of course.
