Why is a ball-peen hammer round?

What is hard peening?
“Hard shot peening” is defined as a high intensity peening with an arc height larger than O. 6mmA and using hard shot media such as HV550 or higher. It is well known that hard shot peening provides high compressive residual stress in a thin surface layer and results in remarkably high fatigue strengths[4], [5] and [6].
