There are 7 main types of retouch. These have been defined by Tixier, Inizan and Roche 1980, 92 and Bordes 1961, 9-10 as scraper retouch, parallel retouch, sub-parallel retouch, and scalar retouch, with additions noted by Brézillon 1977, 109 of fine retouch, abrupt retouch, and invasive retouch.
To indicate where the retouch is found on an artifact another set of terms is used.
