"Wow! That is pretty cool. So, it is raw chert, huh?"
"Yeah, it is raw something or other - maybe agatized coral - I cannot swear that it is chert."
"So, are these the last stages?"
"Yeah, pretty much the last stages. I have just started working on developing the very end stages. As you can see, there is virtually no pressure involved in all of that fine flaking. If you run through the archaeological records of cut antler tine tips, you will never get to the end of all the instances that have been recorded. And, that is what I used here, the same old cut antler tine tips that have been recovered thousands of times, from archaeological contexts, in the Americas, over the last hundred years, or so."
"So, you are using archaeologically documented tools?"
"Yes, tools that have been documented probably thousands of times. It was actually well known to past archaeologists, in North America, who did a lot of digging."
