“Due to the ultra-premium titanium material and the finish used for the Great Big Bertha irons, they will be susceptible to bending marks near the hosel when custom lie or loft angles are requested. These adjustments will not affect the integrity or durability of the head in any way, only the surface layer area where bending occurs.  Callaway Golf does not warrant its products against damage caused by third parties. This warranty does not cover paint scratches, cosmetic blemishes or other normal wear and tear. These marks will not affect performance, integrity, or durability." - Callaway Golf

This is the titanium iron reinvented--Callaway’s first ultra-premium multi-piece, titanium design. We are combining driver-like power with the precision of an iron. By combining our titanium face and body with up to 145g of tungsten, we’ve reached a new level of speed, forgiveness, and overall performance. This multi-material construction creates lightweight power for effortless distance and control.

LIGHTWEIGHT POWER FROM A FORGED TITANIUM FACE AND CP4 TITANIUM BODY

By leveraging materials that are typically reserved for drivers, we’ve generated up to 96g of discretionary weight, and precisely repositioned this saved weight to increase launch and forgiveness. The Great Big Bertha iron features the thinnest titanium face we’ve ever used in an iron. On top of that, it’s also the lightest. The Commercially Pure Grade 4 (CP4) Titanium body flexes more at impact than traditional steel and works together with the thinner face to transfer more energy to the ball. We’re providing legendary driver performance in an iron.
