The biggest part of authentic points I find look pretty crude by today's standards, but they obviously got the job done. An ugly point will kill you just as dead as a purty one. I don't think the old ones were as worried about aesthetics of flintknapping as we are-they just wanted a point and a sharp edge. There are exceptions of course, like some of the paleo stuff, the big Ross blades, Sloan Daltons, or other grave goods.
