Aborigines were the earliest culture to use stone tools.
They used stone axes and adzes as well as knives and scrapers. Knives and scrapers were made from flakes of stone. The flakes had extremely sharp edges.
Flakes could be used for finishing wooden tools like spears and axe shafts or for working with animals skins. Flakes blunted quickly and had to be replaced often.
In a small overhang near the Upper Wolgan River, the discarded flakes from an Aboriginal Tool Factory can be found just as they were left, long ago.
