When I began my more productive hobby of flintknapping, I made the decision to never utilize the many unfinished aboriginal blanks I found while hunting projectile points. I studied them in all conditions of completion to better understand how I could replicate the originals.
I, too, am a fan of Mark's work as he has saved the bacon for me on a couple of projects. As for George's "productive" hobby of flintknapping, it is more appropriate to describe it as "cutting edge". I've seen his work and he is the Rodin of flintknappers. I'd ask him to post photos of his work, but that involves a lot of technological work for a self-proclaimed, modest caveman.
