Amazing discovery. Just as I guessed it was the hollow ground edge in a diagonal flake knocking the edges off. Lucky for us we can see the dive and the removal of a small part of the edge. This is why an Anvil stone will not solve the issue; in this case the avnil stone is only witchcraft. The reason is that an anvil stone can't stop a wave below it. There would be a space because of the hollow ground surface.
Here is the solution. ....I have not developed one yet but the first step was to understand the why.
I have a ton of photos to demonstrate what happens to a wave under so many conditions and I will post them as well but first the cool stuff.
In the photos the white stone has be covered in graphite. The first 4 photos show the stone before the flake was taken. The next set of photos shows a flake traveling across to the other side and steps as it is redirected to the edge and then dives causing a very small hinge. The photo with the pencil show the location of the small dive. This is all on a small scale but should work to help people understand why this is happening.
Now remember this is small but when it is large it is a real pain.

Ok the results

iowabow:
So if you want to induce an edge to dive off drive a Ridge to a hollow ground edge and when it encounters the extra mass then snapppOooo

iowabow:
The extra mass I am talking about are the ridges and up turned surfaces. When the diagonal flake reaches the horizontal flakes that are hollow ground it becomes too much and the energy dives.

iowabow:
This is an old point I made but had many problems building it so with this new mindset it should be easier that all this post is about .
