It had become common practice in the Middle Palaeolithic that not only the block of the raw material was made into a tool by flaking (e.g. chopping tool), but humans also formed a variety of tools (spear tips, scrapers, burins) from the different flakes stroked down from the stone core.
With the reduction in the size of the stone tools, their production became more profitable, their transportation became easier, and more tasks could be solved with them.
