Mineral winning pick, holder, and combination
A pick for mineral winning includes an elongate shank configured to be positioned into a cavity of a holder. A profile is defined on an outside surface of the shaft which includes a first surface formed into the profile and disposed to receive a leveraging device to enable a first forced translational movement of the shaft relative to the holder, and a second surface formed into the profile and disposed to receive the leveraging device to enable a second forced translational movement of the shaft relative to the holder.
