The Key Mk.3 Note: The base kit doesThe original Key integrated an 83mm conical burr set into the most compact, space saving design possible. The Mk. 2 marks an evolutionary step in the development of the Key by introducing significant usability and workflow upgrades while maintaining the same footprint as the original version. The burrs and mount define the width of the Key, so it takes up a fraction of the space required by grinders with burrs only a fraction of the size.
