the only one of you that knows anything about hammers ! It's not a ball and peen hammer,the ball is the peener.
The original function of the hammer was to "peen" riveted or welded material but today, the ball end of the hammer is most commonly used to expand and shape the free end of copper roves, light rivets and similarly, "setting" the rivet in place to complete the joint. Peening is also the method by which steel drums are formed and tuned.
A ball-peen hammer is also known as an engineer's hammer or a machinist's hammer and may be graded by the weight of the head. It is the mechanic's hammer of choice when making gaskets or driving drift pins
