I think also of the saber-tooth tiger -- what were those extraordinarily large teeth for? Digging, like the walrus?
Predators have sharp teeth right? So they can rip the prey apart and get it into their stomach in tiny bits.
Did you ever try to break something hard between your sharp teeth? If you did I am sure you know that after the thing broke, your teeth will slam onto eachother pretty hard. If you would do this very often, you would break or at least ruin your teeth.
So the teeth of predators are really not suitable to crack nuts. You don't crack nuts with a knife either after all...
