There were years when I thought that a factory grind was the best edge you could get. I've since learned better. This is a chisel that I bought last week. As I was in the midst of honing it for the first time, I noticed that I could see the lines from the factory grind. Hence the picture. Those lines indicate an uneven edge to the chisel. My honing was eliminating them, creating a uniformly flat surface. Further honing, with finer grit stones, will make that edge more polished. In other words, a sharper edge.
