I had this one sitting on my desk for a few years now waiting to get the courage to finish it up.
I don’t know what type of material it is. I got it from Frank a long time ago. It knaps good but the black acts slightly different than the white. I had some steps in the black but I was pretty wide yet.
Decided to give it a try. I worked my center line towards the step side of my biface and narrowed it up a bit. Set up a couple platforms and made it look a little better.
I’m pretty happy with it now. Not perfect but I figured out a few things working it.
