Mr. Hise
I looked and it seems that one side of the blank wall is thicker than the other side; I assume the thicker side would be the spine? It was a fairly clean break and nothing looks odd to my uneducated eye. I did notice that the break was above the sanded area, so that eliminates the over sanding theory. I spoke with the manufacture this afternoon and they are sending a replacement. They said they had not heard of their blank breaking in the described manner.

I am taking it that the spine is not as important at the butt, and critical at the tip section?
