An imprecisely defined elongated flaked stone artifact with dorsal ridges associated with sub-Saharan African Middle Stone Age collections. Unlike true blades, flake-blades do not necessarily have parallel sides, nor are they necessarily at least twice as long as they are wide. They were usually end-struck off cores, frequently taper to a point to form artifacts termed convergent or pointed flake-blades, and often have faceted platforms. Some examples were retouched to form knives or denticulate or notched tools.
