7. As good a speculation as any I suppose.
Perhaps it lead to deliberate attempts at producing cutting tools by throwing/dropping rocks and small boulders onto hard surfaces.

One would also speculate that eventually one noticed that certain types of "glassy" stone produced sharper and more consistent prototools.

This method of making/finding tools by picking through the shards of a broken boulder would also explain why there is such a large gap between the earliest evidence of tool use and the advent of obvious tools in the fossil record. The tools are there, there is just nothing about them that recognizably makes them a tool.
