ABSTRACT:
A ski-pole or crutch is provided with a forearm yoke at its upper end and a pistol grip spaced below it. Both the yoke and pistol grip face rearward so that when the pistol grip is held in one hand the yoke can be swung into and out of locking engagement with the upper side of the forearm simply by bending the wrist, thereby providing greater maneuverability of the pole and support of the arm when needed for balance, support of the body and steering by planting the pole or dragging it.
