Image: Stone tools: initial reduction flaking
Initial reduction flaking is when the chosen stone is held in one hand and struck forcefully with another hand-held stone, called the hammerstone, or the chosen stone is struck onto an anvil stone. This action will detach a flake that can be worked further and also results in a sharp edge on the chosen stone, making a chopper or core tool. This technique was primarly used to produce Oldawan tools and as a first step in the prodcution of more advanced tool kits such as Modes 3, 4 and 5 technologies.
