Pressure flaking technique in retouch continued to be used in the Cobble Paved Building Subphase and was not different from the Channeled Building Subphase, but this technique disappeared after the Cobble Paved Building Subphase - at the beginning of the 8th millennium cal.BC. The dominant tool set of this stage started to form in the Cobble Paved Building Subphase and became highly standardized in the Cell Building Subphase when reserve stocks of flint and obsidian were kept in the cell buildings.
