two hundred and first Post. Core edge blades.
basic component of a controlled blade production is the Leitgrat, which can exist either as a natural edge, for example, between cortex and divide space, or a stuffed ridge (Hahn, artifact morphology 1991) The ridge is called Leitgrat prepared. Since the preparation of Leitgrats impact direction is perpendicular to the future, they can be easily recognized preparation waste. Because of the negative and the nature of the degradation they can be divided into natural, primary and secondary core edge blades.
to be differentiated further, cause here but too far would. Than merely advance preparation they were rejected not always easy, but were also used as tools, for example with additional dressing as a drill or scratches are virtually specific evidence of the mining techniques and tools simultaneously. The striking blade negatives, single or double fall immediately so that they can not be created at the impact blade as retouching. In such experiments would break the blade.
