That makes sense. OED lists zillions of spellings, but it does define peen as "end of a hammer head opposite the face; (formerly) spec. the sharp or thin end." So we can both be correct. :-)
That's quite possible; it's years since my dad taught me all this stuff. And the thing that makes me think you're right is that one of the hammers was the "ball pein" hammer (yes, different spelling), which had a rounded, mushroomy striking surface opposite the regular flat one. And then there was the "claw hammer", which was much better at removing nails. I have probably been misled by the name of the ball pein hammer into thinking that peins/peens are by definition rounded.

Isn't it still called a peen, though, despite the shape?
Unless it's a claw hammer…
The end of a hammerhead opposite the face (striking side)
