Scarcity of raw material, leading to the risk of failing to supply the technology needed for optimal resource harvesting, is seemingly a function of the distance between the place of raw material procurement and its place of use. Because the distributions of raw material and subsistence resources normally do not overlap, some curation of the former is expected to occur. Bamforth (1986) modeled two curational behaviors—recycling (“remaking of an implement into a different kind of tool”; Odell 1996:59) and maintenance (a behavior designed to extend the use life of an artifact; Shott 1989a).
The predictions are then compared against the data from the flaked items. In a similar manner, it is possible to compare the characteristics of retouched and unretouched artifacts in order to identify and understand selection patterns. However, these are not perceived, or treated, as rigid, formal behavioral categories (in the sense of Tostevin 2000, 2003); hence the flexibility and variability of knapping procedures are not masked by preconceptions about the behavioral significance of the technological procedure.
This will respond to the need to minimize transportation costs. But the further away a consumer site from the source of raw material, the greater the need to curate the nodules or blanks, to compensate for unavailability of raw material and to delay future costly trips to the source. This requires that blanks be larger so that they can be retouched and maintain serviceable dimensions. Thus, the second hypothesis derived from Munday’s raw material model predicts that longer blanks will be preferred for retouch, regardless of a site’s proximity to raw material sources (Munday 1976b:134–138; Crew 1976; Marks 1988).
