A uniflex steel shaft is the most commonly sold and used golf club shaft, due to its ability to give average golfers with slow golf swings better results. Uniflex steel shafts also allow beginners and average golfers room to improve by increasing in stiffness as their golf swing speed increases.
A club shaft's flexibility rating indicates how much it will bend during the downswing. Most golf club manufacturers classify their club shafts using a letter scale, in which 'L" represents the most flexible shaft and "X" represents the stiffest shaft. Uniflex shafts are in between L and X on this scale, which signifies their ability to accommodate a very broad range of swings.
