Callaway Big Bertha Iron Set 4-10 plus PW with Steel Shafts

Callaway Big Bertha Irons

---

The new irons incorporate Callaway's proprietary notching weighting system for an increase in forgiveness and accuracy. This is the process of moving weight from the center of the club and relocating to key areas of the heel and toe and across the back ribbon area. This allows for maximum perimeter weighting helping to square up the clubface, especially on off-center hits.
