The Big Joe is the larger of the knobs offered by Comandante, and makes a sizable difference for those with big hands. At 55mm compared to the 44mm standard knob, the added size can make a noticeable difference when using a Comandante C40 MK3 or MK4 hand grinder to ground your coffee as evenly as possible.
This black knob is made of oak and easily mounts onto the crank with a push-button mechanism, and can also be removed just as easily.
