Listen I don't mean the naked nut.
I mean before their removed from their husk.
Example:

They can be bigger if you let them grow for a while in a natural habitat rather than some walnut farm or something.
you still dont seem to be getting that a nut the size of a quarter can only be thrown so fast. a pebbel is small but if someone slingshots it at you, it's going to bruise you or take out your eye. if someone throws a walnut at you it's going to bounce off you. your arm can not apply the same kinetic force a loving slingshot can so you can't KO someone with a walnut, or even bruise them with it. get this through your loving head.
I'm not talking about the small quarter sized nut on the inside.. How many times do I have to say that?
I'm talking about whats in the picture above.
