Australian archaeologists have often described the form as a leaf-shape. While this description is in someways apt, it fails to depict the great diversity of point shapes that can be found. Archaeologists have described the variation in points in a number of ways. Most common is the division of points into two main types, based on the direction of retouch along the lateral margins. When the retouch occurs on only one surface the specimen would be termed a unifacial point , but if retouch scars occurred on both surfaces it would be called a bifacial point .
Points also vary in their narrowness and elongation, when viewed from either face.
Although it is carefully shaped this point is very wide relative to its length. This specimen has a length approximately twice as great as its width, giving it a more narrow, more elongated look. An extremely long, pointed look is found in this specimen, which has a length about three times greater than its maximum width. While these kinds of variation have sometimes been seen as a reflection of the preferred style of the knapper it is clearly related to other factors as well. Two obvious causes for variation between points are 1. different raw materials and 2.
