Yup. That top pic is exactly what Bob says he felt when he (gingerly) ran his finger along the edge searching for a burr. He wants to know what kind of camera you used because this was not visible to our *cough* mature eyes.
It just a Canon pocket video cam. I think I shot through a loop that I look at edges with. Naked eye is really hard to see. Might look like wax, but I assure you there was no wax.
