With the introduction of its RAZR X club line, Callaway has embraced even more fully the concept of integrated hybrid/iron sets. Start with the trio of iron models it released in February. The RAZR X irons feature a proprietary technology that shifts the center of gravity lower and deeper in the club head for greater distance and forgiveness. That advance is coupled with Callaway’s Variable Face Thickness Power System in an effort to more precisely position mass properties to maximize ball speeds.
The RAZR X Tour irons utilize the same RAZR and VFT technologies but offer a more compact head shape with less offset and a thinner top line. The idea here is to provide even more of the workability and sleek look preferred by better players.
Then, there are the RAZR X Forged irons, which are made of forged 1020 carbon steel and have been played on professional tours since late last year. Designed to create soft and responsive feedback, they boast a higher, squared-off toe and a sharper leading edge as well as a thin top line, narrow sole and short blade length.
“RAZR technology is a breakthrough in iron design for Callaway,” says Alan Hocknell, senior vice president of research and design for the company. “Most irons today are designed for one specific performance benefit – distance, forgiveness or feel. But RAZR allowed our engineers to combine those into a complete package. In the RAZR, we’ve created the ideal iron for golfers looking to make the jump from being a high handicap to a single digit player. And with RAZR X Tour and RAZR X Forged irons, we incorporated feedback from accomplished golfers as well as Tour professionals like Phil Mickelson.”
According to Hocknell, Mickelson also had a lot to do with the new RAZR X and RAZR X Tour hybrids, which were developed from prototypes he and other Callaway staffers used in competition. The standard model RAZR X has a clubface with a Zero Roll design, for higher launch angles on shots hit low on the face so they fly farther and land more softly. It also features an offset hosel, which is its biggest difference from the RAZR Tour X hybrid; that model employs less offset for enhanced workability.
The RAZR hybrids are available in lofts of 18, 21 and 24 degrees (Tour version) and 21, 24, 27 and 30 degrees (Standard). As for the RAZR X, RAZR Tour X irons and RAZR Tour Forged, set configurations are available in 3-PW or 4-AW and come in steel or graphite. An integrated set is available with steel shafts and two RAZR hybrids replacing two irons.
