I just downloaded (thanks to other commenter below) and would question the "use" part. What is the "peen" end used for? Having read the section on hammers I still don't know. (Just re-skimmed the section and I still don't know.)

I dimly recall making an ashtray (hmmm, not sure that would fly these days) in high school metalwork class by beating out a piece of copper sheet with the peen until it was suitably concave.
