In the archaeological collection of the National History Museum of Azerbaijan there are stone tools from all cultural layers of the Palaeolithic cave site of Azykh. Among these artefacts, there are three 4-5 kg weighing stone implements discovered during 1974 archaeological expedition led by Mammadali Huseynov. Found on level VIII of the cave’s cultural layers, the tools are conventionally named as gigantoliths or gigantolith choppers. One of the tools are currently stored in the Museum’s archaeological fund. Discovered in the cave’s bottommost layer, the chopper is an interesting and rare labour tool – one of the earliest tools used by the cavemen by holding it with both hands.
