scalarret
Scalar retouch, or scaliform retouch type, is a semi-abrupt form which fractures on the end of the removals in steps or scales. It is a more extreme form of scaled retouch and the depth and angle of the detachments imply the use of a dense or sturdy percussor (Bordes 1961, 9-10; Tixier, Inizan and Roche 1980, 92). It has been successfully duplicated by using the central section of a wooden baton percussor and striking abruptly onto the edge chosen for modification. Scalar retouch can be applied to thin blanks, but because of the depth of the removals a thick blank is often used.​

Scalar retouch is also called Quina retouch as it application is characteristic of this Middle Palaeolithic, or Mousterian, industry. See Brézillon 1977, 112.
