I'm looking at a cast of a Deinonychus claw right now, and compared
to the general shape of theropod claws from the manus it is quite
distinctly thin and blade-like. I doubt it bore a razor edge, but
I can see it being forced in between the ribs and creating havock
with the internal organs. It seems to form a more open curve that
the tighter curve of a grasping claw. So if its main purpose wasn't
grasping, what else would it have done but slash? Unless it was purely
there for attracting females (ie. the biggest claw gets the girl), in 
which case we are all off the mark.
