Chopping tools (choppers, pebble tools) are the oldest human implements. They were produced and used for the first time by Homo habilis during the Lower Palaeolithic. The richest tool industries of this type come from eastern and southern Africa (Olduvai Gorge). Chopping tools were also used to a lesser degree during the Middle and Upper Palaeolithic. Nevertheless, this tool type survived through later periods as well.

Their production required the use of river or lake pebbles from different rocks. The working of the raw material included the remove of a flake by using a chopper. Removing more flakes from the same side of the pebble produced a chopper. Using further the already worked surfaces as percussion platforms, a bifacial chopping tool was produced. The types, the weight and the dimensions of these tools varied. Their length did not usually exceed 20 cm.

The chopping tools, collected in the Greek area, belonged to the tool industries of the western Peloponnese (Heleia, Achaia) and the Ionian islands, and date to the Middle Palaeolithic. A chopper from the region of Lake Korissaia in Corfu is the only find which could date to the Lower Palaeolithic.
