I never meant to suggest that it was impossible, just bad for your teeth... I thought that if you had to crack (many?) nuts like that every day, your teeth would soon be a goldmine for the dentist.
Sugar and other factors contribute to tooth decay. I suppose if you spent all your time cracking nuts with the "wrong" teeth you could wear them down to the gums, but we don't and never have lived on a diet of nuts. BTW, have you ever noticed walnuts have a seam? You can also crack the shells of some nuts with your hands. About the only nutmeat I don't think anyone would want to attempt to crack the shell or pod of in his or her mouth is the cashew. It is enclosed in a poisonous liquid. (A useless bit of trivia)
You are absolutely right there, but tuppence suggested that tigers used their teeth to crack nuts or something like it. Tigers couldn't use their claws to crack nuts I would think, so all they have is their teeth....
