Tool is not a band.
== Types ==One can classify tools according to their basic functions:Cutting and edge tools, such as the knife, sickle, scythe, hatchet, and axe, are wedge-shaped implements that produce a shearing force along a narrow face
Substitution is "makeshift" when human ingenuity comes into play and a tool is used for an unintended purpose such as using a long screw driver to separate a cars control arm from a ball joint instead of using a tuning fork
