No, I'd still use the diamond. About 800 to set the edge and 1200 to finish. The most important thing is to sharpen the whole bevel. You've got to take off a lot more metal, but getting the right angle is foolproof. Sharpening a secondary bevel will about ruin it.

Something kind of funny, after going through the whole polish and then stropping the blade, Ray used the edge of a car window to give it some "tooth".
