That's fascinating. I've seen plenty of arrowheads in the U.S. that were flaked from obsidian or other hard rocks, but I have never read about how these Khoisan stone blades were made.

This fine grained quartz used here is very like obsidian, just is a bit more difficult to work and does not produce blades that are as long as with obsidian. Obsidian is pretty rare in most parts of Southern Africa so you have to make do with what's available.
