Object used for some purpose outside the individual that is used to modify or manipulate something else in the environment; precludes simple environmental shaping. Any object that aids in the accomplishment of work; typically, an implement makes a task more efficient. Diagnostic features of a flake tool, as opposed to a geofact, include the striking platform, the bulb of percussion, the bulbar scar, ripple marks, fissures, and dorsal scars. Among the telltale features of a core tool are the cortex, the flake scars, and the negative bulb.

Cf. implement.
