“ The secret of striking the round blow safely lies in the position of the knuckles. Just as in true cutting with a sword, the elbow and knuckles are the test. Ask an unskilled man to make the "cut one" with a sabre (from right to left, horizontally) , and he will, assuredly, cut with the back of the sword for two-thirds of the distance. Simply because he keeps his elbow and his knuckles turned up instead of down. And so with all sword-cuts. So, too, with the round blow in boxing. ”
