Abbevillian tools, named for those found in the Somme Valley near Abbeville in France, are typically massive core tools or double-faced hand axes (known as bifacial-tools). They are produced by knapping away flakes from opposing sides of the tool to give a jagged or curvilinear cutting edge. The tool was made from flint, chert (chalcedony), jasper, obsidian, and even coarser-grained quartzite.
Abbevillian tools are closely related to but typically less complex than Acheulean tools. It is considered by some archaeologists to be an early variant of Acheulean industry.
