My current project brought something to the forefront recently.
Most of the used hollows that have come my way have unevenly honed irons. Most likely caused from it being easier to sharpen the middle of the curve than it is the edge. What happens is the edges become sharp points that can dig into the work at the edges.
My camera wasn't taken out to the shop the last few days so maybe some pictures later.
