Tools, Machinery, and Other Durable Equipment.

A tool is any physical item that can be used to achieve a goal, especially if the item is not consumed in the process

Tools that are used in particular fields or activities may have different designations such as "instrument", "utensil", "implement", "machine", "device," or "apparatus".

Cutting and edge tools, such as the knifescythe or sickle, are wedge-shaped implements that produce a shearing force along a narrow face. Ideally, the edge of the tool needs to be harder than the material being cut or else the blade will become dulled with repeated use.
