I didn't think of that is guess "a good point is a beauty forever". Early man never ceases to amaze me.
Some of those early points display amazing craftsmanship. Even today I see them in a museum or collection and think of them as functional art. Having learned how to flintknap (poorly, I might add) I also know the effort that went into them--getting the proper stone, possibly heat-treating the stone, then the actual work to craft the point. I have a book at home that shows some of the most impressive points. I'll dig up the reference tonight if you are interested.
