Cleavers, found in many Acheulean assemblages such as Africa, were similar in size and manner of hand axes. 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.
Some Acheulean tools were sharpened instead by the removal of a tranchet flake. This was struck from the lateral edge of the hand-axe close to the intended cutting area, resulting in the removal of a flake running along (parallel to) the blade of the axe to create a neat and very sharp working edge.
The Lower Paleolithic (or Lower Palaeolithic) is the earliest subdivision of the Paleolithic or Old Stone Age.It spans the time from around 3.3 million years ago when the first evidence for stone tool production and use by hominins appears in the current archaeological record, [1] until around 300,000 years ago, spanning the Oldowan ("mode 1") and Acheulean ("mode 2") lithics industries.
European iron of the period contained a high amount of sulfur and when compared to the high carbon steel produced by Kongo iron processes, was less durable, a "rotten" metal. European iron was the second choice, whether the purchaser was from Asante, Yoruba or Kongo. The key to the gradual acceptance of European iron was ecological disaster.
Tool use has been reported many times in both wild and captive primates, particularly the great apes. The use of tools by primates is varied and includes hunting (mammals, invertebrates, fish), collecting honey, processing food (nuts, fruits, vegetables and seeds), collecting water, weapons and shelter.
A hand tool is any tool that is powered by hand rather than a motor. [1] Categories of hand tools include wrenches, pliers, cutters, files, striking tools, struck or hammered tools, screwdrivers, vises, clamps, snips, hacksaws, drills, and knives. Outdoor tools such as garden forks, pruning shears, and rakes are

The Awash Valley. The term "Middle Stone Age" (MSA) was proposed to the African Archaeological Congress by Goodwin and Van Riet Lowe in 1929. The use of these terms was officially abandoned in 1965, [8] although the term remains in use in the context of sub-Saharan Africa, beginning with a transitional late Acheulean period known as the Fauresmith industry.
