About the Callaway Apex 21 Single Iron

The Callaway Apex 21 Single Iron features "A.I.-Designed Flash Face Cup" technology. This design utilized artificial intelligence to create a clubface with variable thickness patterns tailored for each specific iron. The Flash Face Cup technology enhances ball speed across a wider area of the face, improving distance and maintaining performance on off-center hits. This design allows the face to flex more effectively at impact, resulting in better energy transfer to the ball and more consistent shot trajectories. The optimized face geometry also contributes to higher launch angles and better control, making the Apex 21 Irons forgiving and versatile.
