Traditional Cobbler's hammer...?


Howdy,
I would like to know more about the use of the traditionally shaped Cobbler's hammer. They typically have a round head, and a drooped, flat area opposed to the round face.
What is the function of that flat "hooked" part of the hammer?
Thanks for any information on this,
