What was found, in the Cango Valley along with Circular stone hearths and calcified dung remains of domesticated sheep, that is a cutting tool shaped somewhat like an axe that dates back to the stone age?
The adze
Adze
The adze ( ; alternative spelling: adz) is a cutting tool shaped somewhat like an axe that dates back to the stone age.
 It can be any tool with a sharp cutting edge.
 Adzes are used for smoothing or carving wood in hand woodworking, similar to an axe but with the cutting edge perpendicular to the handle.
 Two basic forms of an adze are the hand adze, a short handled tool swung with one hand, and a foot adze, a long handled tool capable of powerful swings using both hands, the cutting edge usually striking at foot or shin level.
 The blade of an adze is set at right angles to the tool's shaft (like a hoe or plane), in contrast to an axe's blade, which is in plane with the shaft.
 A similar, but blunt, tool used for digging in hard ground is called a mattock.
Boomplaas Cave
Boomplaas Cave is located in the Cango Valley in the foothills of the Swartberg mountain range, north of Oudtshoorn, Eden District Municipality in the Western Cape Province, South Africa.
 It has a 5 m deep stratified archaeological sequence of human presence, occupation and hunter-gatherer/herder acculturation dating back 80,000 years.
 The site's documentation contributed to the reconstruction of palaeo-environments in the context of changes in climate within periods of the Late Pleistocene (12,000 - 80,000 years BP) and the Holocene (since 12,000 years BP).
 The cave has served multiple functions during its occupation, such as a kraal (enclosure) for animals, a place for the storage of oil rich fruits and as a hunting camp.
 Circular stone hearths and calcified dung remains of domesticated sheep as well as stone adzes and pottery art (painted stones) were excavated indicating that humans lived at the site and kept animals.
Gull Island (Prudhoe Bay)
Gull Island is a small island located at , 8 km (5 miles) off shore from Prudhoe Bay, Alaska, in the Beaufort Sea.
 In plan view it is shaped somewhat like the capital letter "L", with a length of approximately 300 m, and is about 30 m wide along much of its length.
 In some satellite images it appears like a small crescent, due to its low topographic prominence above sea level.
 Little more than a gravel pad, it is a roosting place for seagulls in the summertime.
 It was also the site of petroleum exploration as part of the larger Prudhoe Bay Oil Field exploration in the 1960s and 1970s. Lake Moody
Lake Moody is a natural freshwater lake with a 409 acre surface area.
 Shaped somewhat like a flint arrowhead, Lake Moody is in an area of sparse residential development.
 A scattering of residences, as well as citrus groves, are on the south side of the lake along South Lake Moody Road.
 On the west side the lake is bordered by the Scenic Route of Highway 17.
 A few residences line the west side of the highway and the shore on west side is all private property.
 Most of the area along the highway is bordered by citrus groves.
 North Lake Moody Road borders the northwest part of the lake.
 The shore borders much of the road right-of-way on this road.
 Lake Moody is bordered on the northeast by citrus groves and some swampy areas of ground.
 A railroad line, more swamp and citrus groves line the east shore. History of the domestic sheep
The history of the domesticated sheep goes back to between 11000 and 9000 BC, and the domestication of the wild mouflon in ancient Mesopotamia.
 Sheep are among the first animals to have been domesticated by humans, and there is evidence of sheep farming in Iranian statuary dating to that time period.
 These sheep were primarily raised for meat, milk, and skins.
 Woolly sheep began to be developed around 6000 BC in Iran, and cultures such as the Persians relied on sheep's wool for trading.
 They were then imported to Africa and Europe via trading. Turning
Turning is a machining process in which a cutting tool, typically a non-rotary tool bit, describes a helix toolpath by moving more or less linearly while the workpiece rotates.
 The tool's axes of movement may be literally a straight line, or they may be along some set of curves or angles, but they are essentially linear (in the non mathematical sense).
 Usually the term "turning" is reserved for the generation of "external" surfaces by this cutting action, whereas this same essential cutting action when applied to "internal" surfaces (that is, holes, of one kind or another) is called "boring".
 Thus the phrase "turning and boring" categorizes the larger family of (essentially similar) processes known as lathing.
 The cutting of faces on the workpiece (that is, surfaces perpendicular to its rotating axis), whether with a turning or boring tool, is called "facing", and may be lumped into either category as a subset. Ovis longipes palaeoaegyptiacus
Ovis longipes palaeo-aegyptiacus is a type of the extinct wild barbary sheep found in the ancient Southern Egypt and Nubia.
 The ovacaprines were domesticated and often depicted on the stone tomb murals of the pharaohs for religious or aesthetic purposes.
 "Ovis longipes palaeo-aegyptiacus" was one of the two most commonly domesticated sheep utilized on the reliefs of early pharaonic tombs mostly because of its unique loosely spiraling horns which came out of the sides of the skull.
 A similar form of the sheep called "Ovis platyura aegyptiaca" had horns that developed downward and curled forward. Lithic technology
In archeology, lithic technology refers to a broad array of techniques and styles to produce usable tools from various types of stone.
 The earliest stone tools were recovered from modern Ethiopia and were dated to between two-million and three-million years old.
 The archaeological record of lithic technology is divided into three major time periods: the Paleolithic (Old Stone Age), Mesolithic (Middle Stone Age), and Neolithic (New Stone Age).
 Not all cultures in all parts of the world exhibit the same pattern of lithic technological development, and stone tool technology continues to be used to this day, but these three time periods represent the span of the archaeological record when lithic technology was paramount.
 By analysing modern stone tool usage within an ethnoarchaeological context insight into the breadth of factors influencing lithic technologies in general may be studied.
 See: Stone tool.
 For example, for the Gamo of Southern Ethiopia, political, environmental, and social factors influence the patterns of technology variation in different subgroups of the Gamo culture; through understanding the relationship between these different factors in a modern context, archaeologists can better understand the ways that these factors could have shaped the technological variation that is present in the archaeological record. Bearded axe
A bearded axe, or Skeggöx (from Old Norse "Skegg", beard + "öx", axe) refers to various axes, used as a tool and weapon, as early as the 6th century AD.
 It is most commonly associated with Viking Age Scandinavians.
 The lower portion of an axe bit is called the "beard" and the cutting edge of the bearded axe extends below the width of the butt to provide a wide cutting surface while keeping the overall weight of the axe low.
 The hook, or "beard" of the axe would also have been useful in battle, for example to pull weapons out of the defender's grasp, or to pull down a shield to allow another attacker to strike at the unprotected defender. Drilling
Drilling is a cutting process that uses a drill bit to cut a hole of circular cross-section in solid materials.
 The drill bit is usually a rotary cutting tool, often multipoint.
 The bit is pressed against the workpiece and rotated at rates from hundreds to thousands of revolutions per minute.
 This forces the cutting edge against the workpiece, cutting off chips (swarf) from the hole as it is drilled.
