Having held the claws (well, casts) of Deinocheirus, they are bigass, but they 
aren't really fearsome. Now a Torvosaurus or
spinosaurid or megaraptoran claw: THOSE are scary nasty!

That said, I would say that Deinocheirus used its claws pretty much just like 
Megatherium did. Which is avoiding the question,
because we honestly don't know.

(I'm quite fond of making the therizinosaur-ground sloth analogy, and before me 
Russell & Russell did the therizinosaur-chalicothere
analogy. Hard to disprove, as we can't directly observe the behavior of either 
member of the pair... :-S)
