primitive Pete and the first hammer

Here a certain stone age craftsman by the name of primitive Pete stumbled upon a very good idea. He suddenly realized that by fastening a stick to a rock like this, he could extend the length of his arm like this and thereby greatly increase the force of his blow like this. [Applause] [Music] Thus was born the world's first practical hand tool. Did we say practical? Well, anyway, it was a good idea. In fact, it eventually led to the development of all the numerous sledges and hammers we have today. [Music]
