Abstract
A ski pole formed with a separate handle and shaft. The handle and shaft are held in normal longitudinal alignment for normal use. Means are provided to permit the handle to be moved angularly with respect to the shaft when forces above a preselected minimum are applied to the shaft and handle in different directions. The ski pole thus bends at the handle when a skier holding the ski pole has forces applied to his hand above a preselected minimum. Means are also provided for adjusting the minimum force required to permit release of the handle from longitudinal alignment with the shaft.
