Trying to maximize both the biface and the flake yield is my favorite part of knapping. I'm not sure it's actually maximizing the total yield given the failure rate but it's neat when you can split a rock in two full length pieces.
Very cool looking biface, can't wait to watch part 2. Always wondered 🤔 what you do with all those crud flakes and the unusable stone that's left over?
I throw it away. Down the street, there's a recycle center that takes "natural" material. They pile it up like a landfill. I dump my small flakes and shatter there.
That’s a big ole piece! God dang. I’d would have started sweating as soon as I picked it up. My anxiety would be crawling out of me and my facial expressions would have probably been this 😬😬😬😬😬😬
