This stone was his first hammer.
Sometimes he used a rough stone.
Its rough edges hurt his hand, so he hunted for a smooth stone.
At other times he wrapped one end of a rough stone in grass.
The grass protected his hand.
This was the first handle to his hammer.
Bodo liked to use this hammer.
He liked to use smooth hammer-stones.
But sometimes the smooth stone slipped or bounded back and jarred his hand.
