Order you a xtra course diamond stone and use it until you have a very sharp edge. Then switch to the medium india for a few minutes, then the fine arkansas and DONE !
xtra course diamnond stone was the best thing I bought from KME. Most folks do not use the course stones long enough and think they have established a bevel all the way to the edge, when in fact they have not. I do not leave the xtra course stone until my edge is pulling hair or shaving hair. After that all you are doing is refining and polishing the edge. IMHO the KME system is the greatest tool ever devised on this planet !!! Cannot say enough good about them !!!
