Re: Claws on deinonychosaurs
In the real world, assassins knives are curved. They cut throats
Frank (Rooster) Bliss
Yes, in the real world, many blades are curved. Many swords produced
in the Middle East were curved, as are Western sabers, katanas and many
The curvature on these blades does not help them cut better in cutting
They do cut _differently_ to some extent (ie. they tend to be used with
the main contact point further from the tip), but they do not cut more
effectively. Assassins knives may be curved for handling, or from a
construction standpoint (my knife, for example, tapers on the blade
side more than the side without an edge, so it is curved in profile).
They do not cut more effectively, however.
Also, 'assassins knives' are recurved, not decurved, to the best of my
knowledge, so I don't think they are often claw-shaped. Decurved
knives are produced; I do not know what their purpose is.

Well, two comments on curvature and cutting surface:
1) The cutting surface would only be increased in length if the claw
were curved in the other direction (recurved).
2) The concept of a curved edge (be it a claw, tooth, sword, etc)
adding appreciably to total cutting power by adding edge length is
something of an urban legend. The total amount of 'added edge' is
pretty minor. Curved edges have advantages, but cutting is not one
of them. A straight edge cuts just as well. (I, personally, was
quite surprised to learn this little tidbit).
