s. Bone tools had mainly been made from bone splinters or were cut into a useful shape. Archaeologists are convinced that bone tools were purposefully made by deer antlers cut into shape. The bone was fashioned into tools such as spoons, knives, awls, pins, fish hooks, needles, flakers, hide scrapers and reamers. They made musical rasps, flutes and whistles as well as toys of bone. Decoratively carved articles were also made of bone such as hair combs, hair pins and pendants. Antler is much harder than bone and was used for flakers, points, knives and hair combs. Even the teeth and hooves did not go to waste. The teeth were drilled and used for decoration on clothing and necklaces. The hooves were also drilled and used for decoration on clothing as well as strung for rattles and bells. As an

History

The oldest excavated bone tools are from Africa, dated to about 1.5 million years ago. It is widely accepted that they appeared and developed in Africa before any other geographic region. A very famous excavation of bone tools is that of the Blombos Cave in South Africa. A collection of twenty-eight bone tools were recovered from 70 thousand year old Middle Stone Age levels at Blombos Cave. Careful analyses of these tools reveal that formal production methods were used to create awls and

s. Archaeologists have long believed that Neanderthals learned how to make bone tools from modern humans and by mimicking stone tools, viewing bone as simply another raw material. Modern humans, on the other hand, took advantage of the properties of bone and worked them into specific shapes and tools. A recent discovery of specialized bone tools at two Neanderthal sites in southwestern France brings to light the idea that Neanderthals may have actually taught modern humans how to make specialized bone tools. The uncovering of lissoirs ("polishing stones") at these sites is significant as they are about 51,000 years old, predating the known arrival of modern humans to Europe. Prior to the Industrial Revolution (when machine mass production of sharp tools became viable), many everyday tools such as needles were made from bone; such items continue to be valued today as antiques.

Awls

An awl is as a long, pointed spike generally used for piercing or marking materials such as wood or leather. Bone awls are pointed tips made on any bone splinter. Bone awls vary considerably in the amount of polish from wear, the method of preparation, and size. Bone awls tend to be classified according to the characteristics of the bone used to make the awl. Many bone awls retain an

, or rounded end of a bone. Although authors have differing theories as to the uses of bone awls, the two main uses agreed upon are as manipulators in the making of basketry and as perforators in the working of hide.

Spear points and bipoints

Bone spear points and bipoints have been found throughout the world. A mastodon rib bone found in Washington State was discovered in the 1970s with a broken bone projectile point stuck in it. A 2011 study using radiocarbon dating found that it is about 14,000 years old. This discovery is significant because it predates the arrival of the Clovis people, and may help rewrite human history in the Americas.

Hoes

Hoes fashioned from bison scapula were common cultivating tools among the Plains Village Indians. In particular, it was used for cultivating small garden crops. It continued to be used among these Indians until iron hoes were brought by French traders in the 18th century. Recovered bone hoes range from 40 cm to as small as 15 cm. The size variation is due, in large part, to frequent resharpening. Bone tools were also used for digging up insect mounds for consumption, known as

Musical instruments

A number of different musical instruments have been created from bone. A vulture-bone flute discovered in Europe is currently considered the world's oldest musical instrument. At about 40,000 years old, the instrument dates to the time that modern humans were settling in the area. Researchers argue that musical instruments such as this flute helped modern humans form tighter social bonds, giving them an advantage over their Neanderthal counterparts. In addition,
