    摘要: Profiled grips of a pair of ski poles have recesses for the embracing fingers and an elevation for supporting the palm of the band. Said recesses and said elevation are so shaped that one ski pole grip conforms to the left-hand, the ski pole grip conforms to the right-hand and the inside surfaces of the ski pole grips are smooth.
