Which stone tool was primarily intended for detailed work on organic materials?

The burin is recognized as the correct answer because it is a specialized stone tool characterized by its sharp and pointed edge, which makes it particularly effective for fine, detailed work on organic materials such as wood, bone, or antler. Burins were used to create intricate designs, engravings, and other delicate carvings, reflecting sophisticated techniques in tool-making and a deep understanding of material manipulation by early humans.

In contrast, a core is typically the source from which flakes are struck; it is not designed for detailed work itself. A flake, while sharp and useful, is generally more appropriate for cutting or slicing rather than intricate carving. A blade, although it has a sharp edge, is primarily used for cutting tasks and may not have the fine tip necessary for detailed work that a burin provides. The functional distinctions among these tools highlight their usage and the skills of the individuals utilizing them in prehistoric contexts.
