The manufacturer says that the inspiration of this unique driver shape is based on the Amazonian Black Caiman. We don't know what a Amazonian Black Caiman really looks like, but this is one great looking driver. Several versions of this driver were drafted and then changed using CAD software until the Center of Gravity was optimized for the absolute best results. The elongated head plus perfect internal weighting produces an extremely stable, high MOI design for incredible distance and control. Finishing off this awesome design is a coating (the call Physical Vapor Deposition-PVD) that creates not only the extremely durable finish, but also provides the sharp black appearance! It really looks sharp! Also available in Left Handed (10.5 degree).
