Thanks Jeff. I will try that. How often do I need to use the stone grader? It seems that my stone looses its smoothness rather quickly. I can quickly get a burr and a nice edge on the first 3 or 4 knives but after that it seems to take a bit of work. If I grade the stone again it performs well. I'm thinking that maybe because the stone is brand new that there is maybe a break-in period but that's just my guess.
