I just got the KME yesterday for Christmas, but it is by far my favorite sharpening system yet. However, I'm having an issue I'm not quite sure how to fix. Once I get down to about the 1k or 3k grit Chosera stones I noticed that I was only getting a polish near the shoulder. I looked at my Chosera stones and noticed that they vary in thickness from one end to the other. I flipped the stone in the holder and it moved the polished section from the shoulder to the edge. Now I've got a narrow unpolished section in between the edge and shoulder that I can't seem to get. What am I missing? My progression has been the diamond stones down to 1500 then the 1k, 3k, and 5k Chosera stones. Thanks for any tips/advice!
