Steel iron shafts have dominated the golf marketplace for 75 years. The reason: Consistency and stability. The process for manufacturing steel shafts is easily repeatable, and the performance from one shaft to another is highly predictable.
Who are the obvious candidates to use steel iron shafts? Everybody, says Kim Braly, creator of the KBS steel shaft.
“KBS is sold in 5-gram increments, from 90 grams all the way up to 130 grams,” Braly said. “We can fit any golfer.”
Steel shafts from True Temper and Nippon are available down to the 75-gram range, although individual golfers must decide how light is too light. On the PGA Tour, where swing speeds are among the fastest in the world, more than 95 percent of players use steel iron shafts. Traditionally, skilled players have favored heavier weights – in the 120- to 130-gram range – but interest in lighter weight steel is increasing on Tour and among amateur golfers
KBS’ Kim Braly called the KBS Tour 90 “more of a player’s shaft than a lightweight shaft,” although the shaft appeals to a wide range of skilled golfers. It is a softer shaft than the KBS Tour. Braly said the Tour 90 S is not quite as strong as the original Tour R. That being said, Braly’s recommendation to amateurs is different from often-heard advice: “Use the strongest shaft you can load, not the most flexible shaft you can control.”
