The term alternating retouch position was introduced by Bordes 1961, 29 to describe the retouch found on a group of side scrapers. It has been defined by Tixier 1974, 3 as "retouch which starts alternately from one surface then from the other on the same edge of a flake, blade or bladelet. When identifying this retouch it is essential to assure that it is consistently regular and continuous. As Bordes 1961, 45 warns, this is the most common form of ´retouch´ to be found on pseudo-tools. Strips of edge damage also often appear to alternate from one side of an artifact to the other.
