We have very little idea of the way in which these core-bifaces were used. They have been called “hand axes,” but this probably gives the wrong idea, for an ax, to us, is not a pointed tool. All of these early tools must have been used for a number of jobs--chopping, scraping, cutting, hitting, picking, and prying. Since the core-bifaces tend to be pointed, it seems likely that they were used for hitting, picking, and prying. But they have rough cutting edges, so they could have been used for chopping, scraping, and cutting. FLAKE TOOLS The third tradition is the _flake_ tradition. The idea was to get a tool with a good cutting edge by simply knocking a nice large flake off a big block of stone. You had to break off the flake in such a way that it was broad and thin, and also had a good sharp cutting edge. Once you really got on to the trick of doing it, this was probably a simpler way to make a good cutting tool than preparing a biface. You have to know how, though; I’ve tried it and have mashed my fingers more than once. The flake tools look as if they were meant mainly for chopping, scraping, and cutting jobs. When one made a flake tool, the idea seems to have been to produce a broad, sharp, cutting edge. [Illustration: CLACTONIAN FLAKE] The core-biface and the flake traditions were spread, from earliest times, over much of Europe, Africa, and western Asia. The map on page 52 shows the general area. Over much of this great region there was flint. Both of these traditions seem well adapted to flint, although good core-bifaces and flakes were made from other kinds of stone, especially in Africa south of the Sahara. CHOPPERS AND ADZE-LIKE TOOLS The fourth early tradition is found in southern and eastern Asia, from northwestern India through Java and Burma into China. Father Maringer recently reported an early group of tools in Japan, which most resemble those of Java, called Patjitanian. The prehistoric men in this general area mostly used quartz and tuff and even petrified wood for their stone tools (see illustration, p. 46). This fourth early tradition is called the _chopper-chopping tool_ tradition. It probably has its earliest roots in the pebble tool tradition of African type. There are several kinds of tools in this tradition, but all differ from the western core-bifaces and flakes. There are broad, heavy scrapers or cleavers, and tools with an adze-like cutting edge. These last-named tools are called “hand adzes,” just as the core-bifaces of the west have often been called “hand axes.” The section of an adze cutting edge is ∠ shaped; the section of an ax is < shaped. [Illustration: ANYATHIAN ADZE-LIKE TOOL] There are also pointed pebble tools. Thus the tool kit of these early south and east Asiatic peoples seems to have included tools for doing as many different jobs as did the tools of the Western traditions.
