It is believed that Homo habilis were the first hominids to create and use tools. These creatures lived in Africa about 1.5 million years ago. Homo habilis probably lived alongside Australopithecus. However, their larger bodies and brains would have given them a clear advantage.
Trust men and they will be true to you; treat them greatly and they will show themselves great.
Ralph Waldo Emerson
Medieval knights put shark skin on their sword handles to give them a more secure grip.
