RE: Dynamic modeling deinonychosaur claws

Well said. But I believe that any modelling that does not take into
consideration the piercing and cutting of the skin as well as the
effort to slice through muscle. Just take an old chicken from the
market and compare what it takes to slice throught the skin and muscle
vice just cutting throught the muscle alone. Probably there are other
things to consider, I don't know.
