Gc7 great to see your getting good results since I saw you at the last meet.. When my stone gets dirty from swarf and you will know believe me when it's dirty I use that lil stone that came with it.. I wet the suehiro and that lil stone .. I use the 1k Side first up and down the stone never across as it shows on the box.. Once the stone is clean move up to the 3 k side and do the same thing..
