As one of the best brand golf manufacturer, Callaway has many famous and successful golf clubs. For over a decade, Callaway's signature line of irons, the X Series, has made the company one of the dominant forces in category. From the X-12 to the X-24 Hot, they blended forgiveness and power in game-improvement models, while better-player models incorporated more shot-shaping feel. Maybe you use one of the x series irons. And I still want to say: just say goodbye to x series irons. You can now say goodbye to the X Series and hello to three models of new RAZR X Irons. Yes, there's an X on the back of the club, but these irons are built on a different foundation than their predecessors.The center of gravity (CG) in the new RAZR X is 12% lower and 15% deeper than the X-22, so shots hit lower in the face should fly higher. And because the CG is so low, Callaway designers were able to strengthen the lofts of the Callaway RAZR Xto give you more distance.The same RAZR weight system can also be found in the new RAZR Tour irons, designed for better players and mid-handicappers.The Diablo Octane is configured to deliver unmatched power through superior design, construction and materials. The crown contains 10 million turbostratic carbon fibers that make up 33% of the clubhead, allowing Callaway Diablo Octane Driver to precisely control thickness like never before.Lighter, faster, stronger. It's what makes the all-new Callaway Diablo Octane Driver a revolution. Fueled by Forged Composite, a unique new material from Callaway that allows superior distribution of clubhead mass, compared with all-titanium drivers. The result? A lighter clubhead that retains an extremely high MOI. The Diablo Octane Driver powers drives beyond those of its all-titanium predecessor, the Diablo Edge Driver, by an average distance of 8 extra yards. Experience the most powerful driver ever imagined theCallaway Diablo with Forged Composite.

A lighter clubhead generates a faster head and ball speed, giving you an additional 8 yards in distance over the previous Diablo Titanium driver. 'Hyperbolic Face Technology' strategically shapes the face thickness to create a much larger effective hitting area for amazing forgiveness. Each of the Hyperbolic faces are subjected to a chemical reduction process, which selectively removes unwanted material for precision thickness control and greater ball speeds off the face.
