Haha, that would be a trick! You are quite right about the spalls. Anyone can make a very effective knife blade with just a little basic knowledge of flint knapping. The material makes for some extremely sharp edges, especially obsidian. Obsidian blades have been used for delicate eye surgery. I have heard of a video where a man cleans an entire deer with a knapped blade. I'll have to check youtube.
