"Scrapers ... are unifacially retouched tools with a steep, wide-angled edge that is suitable for a number of tasks, including scraping hides, planing wood or bone, and cutting like a knife" (Whittaker 1994:27[1])
Scrapers are the most common type of tool found from the Middle Palaeolithic onwards. Any tool with scraper retouch on any edge, or combination of edges is a scraper.
There are two main classes of scrapers: end scrapers and side scrapers
Scrapers are retouched flakes or blades which are used for scraping materials like hide, bone or wood (Østmo & Hedeager (red) 2005:330; Whittaker 1994:27).
Scrapers are the most common type of tool found from the Middle Palaeolithic (ca 150.000-40.000 BC) onwards.
There are many types of scrapers, for example endscrapers, side scrapers, disc scrapers, double scrapers and spoon-shaped scrapers (Østmo & Hedeager (red) 2005:330).
Contents
End scrapers
Scrapers that are made on the end of a flake or blade. The retouched end may be the proximal end or the distal end, but the vast majority of end scrapers are made on the distal end, as this does not require the removal of the bulb of percussion. End scrapers are further defined by the shape of the retouched end, being either concave, straight or convex.
When an end scraper has been made on a flake that is wider than it is long, it is sometimes referred to as a transverse scraper.
Scrapers that are made on the end of a flake or blade. The retouched end may be the proximal end or the distal end, but the vast majority of end scrapers are made on the distal end, as this does not require the removal of the bulb of percussion. End scrapers are further defined by the shape of the retouched end, being either concave, straight or convex (Helskog et.al. 1976:34[2]).
Convex end scraper
End scraper which has a retouched end that is convex in form.
Transverse scraper
An end scraper made on a flake that is wider than it is long.
Straight end scraper
An end scraper which has a retouched end that is straight in form.
If the tool blank is a blade, and the retouch is abrupt retouch rather than scraper retouch it would be called a truncated blade.
Straight end scraper on a flake
An end scraper which has a retouched end that is straight in form, made on a blank that is a flake.
If the tool blank is a flake, and the retouch is abrupt retouch rather than scraper retouch it would be called a truncated flake.
Also see Brézillon 1977:122[3]. on types of truncation
Concave end scraper
End scraper which has a retouched end that is concave in form.
Concave end scraper on a flake
An end scraper which has a retouched end that is straight in form, made on a blank that is a flake.
Double scraper
Double scrapers are made on flakes and blades and have convex retouch in both the proximal and the distal end (Østmo & Hedeager 2005:330).
Side scrapers
Scrapers that are made on the side of a flake or blade. The retouched side may be the left edge or the right edge, or even on both in which case it would be called a double side scraper.Side scrapers are further defined by the shape of the retouched edge, being either concave, straight or convex.Side scrapers may be made on blanks that are blades or flakes.
More categories: double end etc
Spoon-shaped scrapers
Spoon-shaped scrapers are large scrapers with retouched, convex proximal ends. They are dated to the Late Neolithic (Østmo & Hedeager 2005:330).
Disc scrapers
A disc scraper has a retouched edge that often encircle the entire piece (Østmo & Hedeager (red) 2005:330).
