Just had three ebay razors honed by Larry Andro. They should be here tomorrow. He told me one had a frown and the other a smile. He was able to correct. I suppose smile is when there is more metal towards the middle and vice versa for frown. They looked great to me before going to Larry however I'm a newbie and did not place them on a flat surface just eyeballed them. How does this occur? Is it a matter of poor honing or a matter of the stone not being lapped properly (which I suppose is a type of poor honing)?
