Hey thanks Eddie, I will try and contact him.
I am still getting familiar with the site.
Bob, I hear ya about the toughness of the lithic.
I must have gotten a couple premo boulders that I made these with.
They were big so I got some awesome spalls off the outer coretex.
Harder to do as I got deeper into the rock. The big ones are 71/2" and
thinner than they look. lol
Paul, thanks for the endorsement.
