The differences between a hand axe and a cleaver is that a hand axe has a more pointed tip, while a cleaver will have a more transverse "bit" that consists of an untrimmed portion of the edge oriented perpendicular to the long axis of the tool.
The Great Rift Valley of Africa provides critical evidence for the evolution of early hominins.The earliest tools in the world can be found there as well: An unidentified hominin, possibly Australopithecus afarensis or Kenyanthropus platyops, created stone tools dating to 3.3 million years ago at Lomekwi in the Turkana Basin, eastern Africa.
Some Acheulean tools were sharpened instead by the removal of a tranchet flake.

Composite microlithic tools were useful for harvesting wild grasses and also permitted the production of fine shell and bone fish hooks, which may have allowed for the exploitation of a broader range of food resources. Some of the earliest pottery in Africa has also been found in the Sahara and is associated with hunter/gatherer populations. [51]
