Here are the pictures of the hammer I used to shape the metal repair pieces for the firewall, mentioned above. I am no body man, novice at this. Using "Metal Bumping" book mentioned by others here as a good resource by Frank T. Sargent for repairing body damage.

The hammer worked well for me using the chisel like end to bend the metal and the round flat end to flatten/ straighten areas as needed.
