The flake could be used immediately for cutting or scraping, but were sometimes modified in a process called reduction to sharpen or resharpen the flake. [ 30 ] 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 ...
Forging uses heat to bring the material to a malleable state.

There is a variety of forging techniques for sword making and many variations upon those. Ceremonial swords from the Philippines.
