Jesse I dont know what it is but one day I was pressure flaking and I was shooting flakes clear across the blade. I was able to do the same on both sides / parallel flaking , and thinning stacks and being able to remove steps and hinges with comfort. I for some reason dont like the small peices of flint anymore and look for to make larger thin blades. Thanks for your comments I appreciate the vote of confidents.
