Abstract: A tool is disclosed for the cleaning of horse' hooves with the tool including a hoof pick pivotally attached to one end of a handle. The hoof pick, when positioned adjacent the handle, defines with the handle an open area through which may pass a tool supporting belt or belt loop enabling convenient attachment to the person. A flexible retainer restrains the hoof pick in both an open position and a closed position. A lock acting on the retainer prevents retainer movement and hence movement of the hoof pick. A finger actuated release disengages the lock from the retainer permitting hoof pick positioning toward and away from the tool handle.
