The longest stainless steel Callaway Diablo Edge irons
Callaway Golf core technologies like VFT, S2H2, a 360-Degree Undercut Channel and Modified Tru-Bore cooperate with each other. This perfects the distance, feel and playability. 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.
