[General] Circular hammers vs square hammers

This one is pretty simple. Why are some famous fictional hammers, like Mario's, circular, and why are some, like Thor's, square? Is one better than the other? Do they have advantages and disadvantages?

Circular ones are for fixing things. No sharp edges, made to not hurt people accidentally. Mario does not use this correctly.

Square hammers are war-hammers, made so that even a near miss will do damage.

They do the same amount of damage if you hit directly on. The square one does more damage on a glancing blow (though Mario is good enough that all of his attacks hit perfectly square on). Round hammers are easier to find, though.
