I have used a softball sized river stone for 15 years. You will need to make some "Dit Da Jow" (bruise wine) to assist with healing and to relieve conjestion in the joints of the hand. Begin training with the stone by tapping with the fingertips and all joints of the hand lightly for anytime you have a few minutes. Increase length and intensity of these sessions over time. In time, your hands will become very hard.
