Hi, I received this hone with a bulk lot of razors. I have honed with Norton, barbers, shampton and coti's before. This feels very hard like a synthetic. Water beads on the top. Has a nice even fine feedback. When rubbed with a Belgian blue slurry stone it produced a red slurry and feels much rougher feedback when honing on the slurry. Touched up a razor on it 100 passes with water and a little pressure hht4 off the stone which is what I normally get. Shaves smooth like a coti, feels a bit finer and more refined than my coti. Any ideas if it's a natural or not ?
