Falcons use the beak to kill.  Buteos and eagles don't.

Gulls, with a curved beak tip, also use the beak to kill, what with
having those webbed feet and all.

That said, the lack of lateral compression in phorusrhacid beaks is
likely a better argument against this mode of subduing prey than the
curved tip is.
