Abstract
Abstract The handle of a ski pole has its grip axis offset from the axis of the shaft of the pole and set at least rearwardly thereof to allow the point of the pole to engage the snow substantially more forwardly than an ordinary pole and thus with a more acute angle. The inclination of the grip axis can be adjusted.
