With all the talk about Abo style knapping & tools lately I've felt a lil left out. 
Iowa has me wanting to try my hand at stone & bone knapping lately.   I started knapping years ago Abo style, but switched to copper a long while back.  
Actually I spall with stone. I have doing it produces a better spall than a large copper spaller. 
I picked up a few large antler pieces & tried to create some Abo tools of my own.  
The pressure flaker is a copy of 2 I know were found in a rock shelter in centeral Tx. 
That thing works better than I expected it to.  I found my hardest hurdle to jump was holding the stone exactly how I would with a piece of belting.   I took some leather scraps I had & used some hide glue to bond them together .  That worked great as well. 
Well here are a few pics of my tools, my piece of stone about 1/2 way through the knapping process,& the finished point.  The style in TX is a Montell point.  
It's 100% Abo style produced
