What best describes a Gravette point?

A Gravette point is best described as a thin blade with a sharp edge and backing for hafting. This specific characteristic indicates that Gravette points are designed for use as spear or arrow tips, which necessitate a sharp edge for piercing and cutting. The backing is particularly significant as it allows the point to be securely attached to a shaft, which is a key feature in the construction of effective weapons during the Upper Paleolithic period.

The other options do not accurately capture the defining features of a Gravette point. The blunt tool mentioned in option B refers to tools intended for different uses, such as processing materials rather than for cutting or piercing. Option C discusses a large, flat tool used for scraping, which suggests a different function that does not align with the specific design of a Gravette point. Lastly, option D describes a simple chipped stone with no specific design, which overlooks the distinctive attributes of the Gravette point—namely, its refined shape and purpose as a hunting tool. Thus, the correct answer highlights the advanced craftsmanship and functionality that characterize the Gravette point in archaeological contexts.
