Callaway Diablo Edge is a long iron
The Diablo Edge irons provide increased distances compromising neither feel nor performance. Its lower, deeper center of gravity (CG) makes the sweet spot more accessible and is in line with where the ball most commonly hit by amateurs on the clubface, generating longer, consistent distance and improving accuracy. Greatest Distance: A lower, deeper CG is designed to make the sweet spot more accessible at lower impact locations. It generates greater, more consistent distance and perfects accuracy for more greens in regulation. Solid Impact Sole: The Diablo Edge irons also feature Callaway's "Solid Impact Sole," designed to improve turf interaction and help golfers who catch the ball fat or thin. They are a game-improvement set aimed at mid- and higher-handicappers.
