Callaway's 2012 RAZR X HL Irons and RAZR X Black driver

At the 2012 PGA Merchandise Show in January in Orlando, Fla., Callaway Golf unveiled its product line for the year. The headliner was the Callaway RAZR Fit Driver. So in this piece, we'll focus on the other parts of Callaway's 2012 line, which includes the RAZR Black X family.

RAZR X HL Irons

Callaway describes the X HL irons as "super game-improvement." They are designed for golfers who need help boosting launch angle and who want ball speed and forgiveness across the clubface.

The Callaway RAZR X HL Irons have an integrated clubface/undercut cavity and the usual Callaway medallion on the back to dampen vibration and improve impact sound. The X HL irons have wider soles.

RAZR X Black Driver

The Callaway RAZR X Black Driver has a black PVD finish and a crown of Forged Composite, the lightweight material developed by Callaway in partnership with automaker Lamborghini.

Something Callaway calls "SpeedFrame Face Technology" creates, the company says, a larger sweetspot and higher ball speeds across the clubface, which itself is made of titanium.

An aerodynamic design of the clubhead means the RAZR X Black driver creates 17-percent less drag in the downswing compared to Callaway's discount golf clubs--Diablo Octane driver, and less drag can help golfers boost swing speed.

Callaway's senior VP of R&D, Alan Hocknell, succintly describes the target audience for the RAZR X Black driver thusly: "The RAZR X Black Driver is designed for the golfer who is hell-bent on ball speed."
