I just finished sharpening most of my larger Spydies and two AFCK's with the 203 sharpmaker and the ultra fine grit bench stone. I only finished with the ultra fine grit on the large AFCK, Starmate, and to repolish the edge of a Calypso Jr. Lt. What a difference! I'm no expert hone, but that ultra fine grit stone gets them scary sharp with a nice polished edge. I didnt think that the grit wsa much finer than the white fine grit stones on the sharpmaker; I'm now a believer.
