When Nippon Shaft’s N.S. PRO 950GH came to market in 1999, it was the first consistently-made sub-100 gram steel shaft in the world. In addition, all Nippon Shaft products are “constant weighted,” meaning that every iron in a player’s bag be it a 3-iron or a pitching wedge weighs the same. Professionals demand constant weighting for the sake of consistency. Amateurs and higher handicappers also can benefit from constant weighting.
