  Callaway Golf was founded by Ely Callaway in 1982, and the company became the world's largest club manufacturer in 1996. Callaway's list of clients has included Arnold Palmer, Annika Sorenstam, Phil Mickelson and Graeme McDowell. The Big Bertha X-12 iron series---introduced in 1998---was made with a larger sweet spot than the standard Big Bertha irons, and it and was redesigned to give a more heel-and-toe balanced club. The X-12 irons provide great control and consistency on shots, as well as allowing a player to get the ball airborne easily.
