Saws exist in many hand-powered and mechanical forms, but all cut through repeated tooth contact. Their rasping, shrieking, or buzzing sounds make them especially vivid in poems of carpentry, forestry, surgery, industry, and domestic work. A saw represents gradual yet irreversible division: unlike a single axe blow, it advances through persistence. Poets may use it to suggest time gnawing through life, civilisation cutting into nature, or labour transforming raw material while producing dust, noise, and loss.

Saw is a broad term covering many toothed cutting tools, including handsaws, bow saws, ripsaws, whipsaws, and powered saws. A poem's setting and sound usually reveal which form is intended. Sawing is gradual, repetitive, and irreversible, so it readily symbolises time, destruction, labour, or separation. The noise may range from a dry rasp to an industrial shriek. Related terms include blade, teeth, timber, metal, sawdust, carpentry, forestry, handsaw, ripsaw, cutting, repetition, division, mechanisation, and human intrusion into nature.
