Callaway Left Handed Golf Clubs|Iron Sets^New and Used Great Big Bertha 23 Iron Set Golf Clubs

Great Big Bertha reinvents the titanium iron. Callaway’s first ultra-premium, multi-piece design combines driver power with iron precision to achieve a new level of speed, forgiveness and performance. A Forged Titanium face and body saves substantial weight to increase launch, with more flex at impact than steel and thinner face for greater energy transfer. The Tungsten Speed Cartridge contains up to 145g of high-density tungsten to deliver the deepest CG ever in a Callaway iron. The Forged Titanium face is designed through A.I. to optimize speed and spin. Callaway’s patented urethane microspheres enhance sound and create a softer feel.

• Tungsten Speed Cartridge – Unmatched level of tungsten creates a 133% increase over Rogue ST Max, the most ever in a Callaway iron
• A.I. Designed Forged Titanium Face – The first Callaway iron to use titanium and industry-leading Artificial Intelligence designs
• Incredible Sound and Feel – Patented urethane microspheres deliver great sound and soft feel, while still allowing the face to flex and generate higher ball speeds
