The surface opposite e border may be flawed to form a sort of backing. In many cases even this surface is composed of e natural cortex. That is, it is a tool type of planning and may carry no evidence of any further working on it.
It is a type which, like the end scraper, is more of an Upper Paleolithic character. In Lower and middle Paleolithic it occurs in generalized forms. It is a type in which a thick projected end of a key is specially obtained by etching out two (ideally) notches at the base. In many cases removing even one notch can serve the purpose.
This is again an Upper Paleolithic type but may be known in atypical forms from as early as late Lower Paleolithic. Burin can be prepared on a flack, blade or even on a core.
The working end is exactly comparable to the same of a screw driver. This 0.5 to 1 cm transverse cutting edge is obtained by the intersection of two plains which meet at an angle. Hence these are also called dihedral angle burins. The two plains are called burin facets and the manner of their preparation decides the sub-type of the burin.
Point in prehistory is often a misunderstood type. There may be many broken flakes or blades which have convenient workable pointed ends (and may indeed, have been used as a point) but such specimens cannot be included into the type Point until they show evidence of deliberate reinforcement on them.
These are triangular flakes in which one of the angles is acute and show reinforcement around the apex. In some special cases retouching may be done along only one border while the other border has a natural fracture. Mousterian point is a very special form of this type known from only some specific areas. The specialty of these points lies in their symmetrical finish with almost all round retouching.
6. Points Leaf Shape—Laurel Leaf, Willow Leaf (Foliate or Blattspitzen):
Back to types again, this is a thin bifacial worked point which is entirely prepared by controlled percussion technique. These points can be differentiated from the leaf points (laurel leaf, willow leaf) in the generalized crudeness of finish in the first place. Secondly, leaf points are prepared by pressure flaking technique in such a manner that the thinning of the body and regularizing the working border are both achieved by the same series of flakes. In Blattspitzen, these are done by separate flakes and hence a large number of tiny step flaking are required in the control of the flaking.
7. Shouldered Points (Dendiculate, Notch):
These are two different types named entirely structurally. Although, all types are structurally defined but the names used to designate them have remained functional just to keep in conformity with earlier literature.
Seen in this regard these types appear both comfortable and also uncomfortable for perception. Comfortable because the name indicated the techno-morphology of the specimen.
A notch is any specimen with a deliberate lateral incurve while a denticulate is any specimen in which more than one notch is prepared along a border. We feel uncomfortable because unlike a Knife’ or a ‘Scraper’ these type names do not appear relevant in our understanding of culture. It is important, therefore, to re-emphasize that types do not attempt to describe a culture. It is that fixed morphological description which helps to identify cultures or culture boundaries from within a complicated spread of activities and their left over’s.
