But Bolo brought some flint stones and set to making his arrows. Then One Eye sat down to show him how to make them more keen and beautiful than any he had ever made. He took a curved piece of bone and chipped off the large flakes. Then he pressed off smaller flakes one by one, working very carefully, until he had made a fine, keen point. Bolo watched his father and worked in the same way, and soon they had a nice lot of arrows. Bolo made a new head for his spear, too, and bound it on with a fresh cord of reindeer sinew.
