Callaway Big Bertha 2006 Graphite Iron Set

• Designed with a 360-degree undercut channel that maximizes perimeter weighting by moving the center of gravity lower and farther back in the clubhead, enlarging the hitting area and stabilizing the clubhead
• Notch weighting redistributes weight to the extreme perimeter to create a higher moment of inertia for greater forgiveness, more stability, and reduced distance loss on off-center hits
• Patented Callaway Golf technologies including S2H2, Tru-Bore and VFT Technology to improve efficiency and feel while taking forgiveness to never-before imagined levels
• Variable Face Thickness technology allows each iron to be cast with less material in the face area, optimizing perimeter weighting for increased forgiveness
• Painted scorelines and sandblasted face assist in alignment
• Constant width sole designed to reduce digging on fat, heavy or chunked shots, the constant-width sole helps the iron move smoothly and easily through the turf
