A kashmiri gentleman taught me today how to break the nut barehanded. God bless him! It's unimaginable that breaking the shell -- to break which, such heavyweight tools like hammers, concrete slabs, furnitures; such complicated contraptions like door hinges; and such tiring exercises like propelling the nuts at walls, are used, and that too with such minuscule success, and with such amount of mess that to salvage microscopic bits of the walnut kernel from the debris so created often makes the act of sacrificing the temptation to try cracking that tough nut look nobler than otherwise -- with bare hands -- even the most femininely delicate ones -- is so miraculously easy!!!
I have decided to tell the general populace about how to do it. And that ways, I will be satisfied that I have already contributed my bit to relieving the world of one of its prime miseries.
Here goes the method!
Place the nut vertically on the table or floor so that it stands on its sharp end. Of course, keep holding it with one hand so it doesn't roll away.
Make a fist of your other hand. Hit the top of the nut with your fist with the little finger end of the fist facing down. Not too strongly, nor too delicately. You will hear a cracking sound. In most cases, it won't be the sound of a bone breaking. It's the nut which is cracked! And that too into two neat halves. All of its soul lying bare in front of you to devour!

Can't believe it? Try it yourself.
