Ski poles are used by skiers to improve balance and timing as well as for propulsion. Early ski poles were simply sticks, then bamboo (1930s), then steel (1940s and early 1950s). In 1958, Ed Scott invented the aluminium ski pole. Now, composite ski poles are much lighter and stronger than aluminium poles, though aluminium poles are still one of the main types of ski pole on the market.
