Most modern ratites will use their feet for defense if they have no other
choice (I'm assuming kiwi's
are an exception!), however cassowaries have specialised inner toe claws
roughly the size and
shape of a large carving knife.
Here's a rather frightening image:
As far as I know, 'terror birds' had no such specialised toe. However ostriches
and emus (which
also lack a 'killing claw') can also do a fair amount of kicking damage. Then
again, they don't have
a terrifyingly hooked beak to fall back on.
