A hawk X10 i assume as it was a while ago? Never heard that an Allegiance looks like them before, the profile is nothing like a hawk, the shoulders are cut totally diffrently, not quite sure what you mean about the rounded toe?
I purposley round the edges so they are not so suseptible to damage when being struck by a ball. If the edges are left square, yes, the look slightly bigger but they have far more chance of cracking when edging a ball.
Glad your friend is happy with the bat, hopefully it will bring him many runs!!
