PLAIN BLADE
You whack with a hammer stone against a bone or antler punch which is directed at the proper place on the blade-core. The blade-core has to be well supported or gripped while this is going on. To get a good flint blade tool takes a great deal of know-how.
Remember that a tradition in stone tools means no more than that some particular way of making the tools got started and lasted a long time. Men who made some tools in one tradition or set of habits would also make other tools for different purposes by means of another tradition or set of habits. It was even possible for the two sets of habits to become combined.
THE EARLIEST BLADE TOOLS
The oldest blade tools we have found were deep down in the layers of the Mount Carmel caves, in Tabun Eb and Ea. Similar tools have been found in equally early cave levels in Syria; their popularity there seems to fluctuate a bit. Some more or less parallel-sided flakes are known in the Levalloisian industry in France, but they are probably no earlier than Tabun E. The Tabun blades are part of a local late “Acheulean” industry, which is characterized by core-biface “hand axes,” but which has many flake tools as well. Professor F. E. Zeuner believes that this industry may be more than 120,000 years old; actually its date has not yet been fixed, but it is very old—older than the fossil finds of modern-like men in the same caves.
SUCCESSION OF ICE AGE FLINT TYPES, INDUSTRIES, AND ASSEMBLAGES, AND OF FOSSIL MEN, IN NORTHWESTERN EURAFRASIA
For some reason, the habit of making blades in Palestine and Syria was interrupted. Blades only reappeared there at about the same time they were first made in Europe, some time after 45,000 years ago; that is, after the first phase of the last glaciation was ended.
