Across northern Australia, especially in Arnhem Land, the "Leilira blade", a rectangular stone flake shaped by striking quartzite or silcrete stone, was used as a spear tip and also as a knife, sometimes long. Tasmania did not have spears or stone axes, but the peoples there used tools which were adapted to the climate and environment, such as the use of spongolite. In north-western Australia, "Kimberley point", a small triangular stone point, was created using kangaroo bone which had been shaped with stone into an awl, to make small serrations in the blade.
