Psychotic linguistic associations

saber > to know > saber > saber-toothed > saber > wise > to know > saber-toothed > long in the tooth > old > wise > hag

I wonder if saber-teeth are called "saber" because they are mature teeth? like, you only get them if you're old and wise and have lived a long time?

I wonder if that's related to the expression "long in the tooth"?

Hmm.
