Back in the dream time my brother found a suitable stone, grooved it, and placed it in the fork of a tree branch, tied the ends of the branch and let it grow in place. I was about 6 years old.. Some years later, the branch had grown around it very tightly and had grown larger. He made a hell of an impressive war club out of it, nobody else had one, they didn't have his patience. He hung it on his bedroom wall with a print of 'An Appeal to the Great Spirit' after he doctored it up with hawk feathers and dog teeth and whatnot. Sure looked good, I don't know if he ever used it in combat.
