40 micron (400 grit) diamond stone > 10 micron diamond paste (a "pea"-sized amount spread on a 8x3" piece of planed hardwood = instant diamond stone) > 2.5 micron diamond paste > and finally a leather strop (from Tools for Working Wood) spread with Veritas green rouge (.5 micron). Whenever the edge needs to be refreshed, I just pull out the leather strop.
