Hey guys, I currently have two sets of clubs. One set has my trusty 710 CB's and the other has the 712 AP2's. Over the years I've noticed the dings and dents that have shown up on both of my forged iron sets but I've noticed that the soles of the AP2's show minimal dings compared to the CB's. Both sets say they're forged and I know that means that they're made from the 1025 carbon steel. My question is are the soles of the AP2's a different material? Even after using them exclusively for 2 years they look excellent. My CB's however look like they get into a fight with each other every night haha. Any help would greatly be appreciated.
