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.

You can now say goodbye to the X Series and hello to three models of new RAZR 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 RAZR X is a game-improvement iron that has a huge hitting area. Replacing the X-22 and X-24 HotCallaway Diablo Octane Tour Driver in Callaway's line, each of the eight irons in the standard RAZR X set are made using a new variable face thickness technology, which makes the hitting area thinner as you move away from the center. This feature broadens the sweet spot and maintains ball speed on off-center hits.

The weight shaved from the face, as well as other none-critical areas, has been placed in a new waffle-patterned, 30-gram weight found in the back of the club.

Luke Williams, Callaway's director of product design, says, "We added the extension to the back, so it's not a part of the sole. It's relieved from the sole so it won't interfere with the way the club goes through the turf." It's also not visible to the golfer at address.
