Hard looking at the photo to see the frown. Is that dark line above the shiny portion of the bevel the marker ? Forward of the heel is the darker part on the shiny bevel shadow or marker ? The razor looks like it has been honed a fair amount and smiling if anything. If the darker spot is marker on one side only that is a PITA. I use a narrow hone and a rolling x for stuff like that. A bit of a warp at that spot if I'm seeing it correctly ?
