A saw is a tool for cutting wood or other material, consisting of a serrated blade (a blade with the cutting edge donated or toothed) and worked either by hand or by steam, water, electric or other power. The saw can also be used for playing music. Though Greek mythology indicates Perdix, the nephew of Daedalos, the inventor of the saw, unearthed constructed wooden artifacts from Ancient and Predynastic Egypt suggest possibly a much earlier date (see [1], Predynastic Egypt).
