Hi - I've been working to flatten the back of an iron. I got to the point where only the corners reflected a little light, and looking at the iron from another angle, I could see a consistent scratch pattern except for the small area at the corners. More strokes, and I had worked out the corners. But as I brought the corners into shape, a bunch of small, faint lines appeared running perpendicular to the scratch pattern I was making. Is this normal?
