I have 3inch wide norton stones and a 1 and a half inch wide bbw coticule kosher combo 5 inch long. my hones are lapped religously with dmt coarse wich does job well. I conducted marker test on a razor i have been honing quite regular. marker was not removing from middle of blade on one side on my norton so i used rolling x and this worked i then used my combo hone and did a couple of passes flat with marker and the marker was completly removed in normal x pattern flat. so i put a pencil grid on my norton relapped to make sure it was flat. i then put marker on my blade, x pattern flat on the norton and the marker did not remove from the same spot i went back to my combo and it removed the marker i tryed on the edge or side of my norton which is what an inch wide and i kept the razor flat and the marker was completly removed this i carn't under stand as any one got any ideas why this would happen i have read that people do prefer narrower hones and some people have there notrons cut down the middle.
