Callaway - 04 Big Bertha Irons - Steel Shafts

The new Big Bertha Irons are the ultimate in forgiveness in an all-steel design with the addition of Notch Weighting Technology. And thanks to the Callaway Golf patented technology built into the Big Bertha Irons, even your fat shots and off-center hits have a chance to become great shots. Notch weighting moves mass toward the heel and toe for increased forgiveness and less distance loss on off-center hits. 360-degree variable undercut channel helps move weight toward the perimeter of the clubhead for enhanced forgiveness and solid feel on every shot. Unique stainless steel irons feature cutting-edge technology for unparalleled shot-making versatility. The Big Bertha 10-iron is part of a new short-iron loft configuration of 9, 10, W, S, and L. New progression eliminates ?gaps? ? especially the large gap traditionally found in iron sets between the pitching wedge and the sand wedge ? by precisely spacing each loft four degrees apart.
