An antler used as a wedge
Some animals had larger and sharper teeth.
The Tree-dwellers found such teeth in the sand.
They found sharp claws there, too.
They often found sharp bones and horns.
They used such things for cutting for many long years, but at last they made a knife.
It happened when Bodo was cracking a bone.
In some way he broke his hammer.
He picked up the pieces and looked at them.
