finally, it may be simple, just sliding it between the stones the whole length but it is too aggresive. The thicker part of the knife towards the handle area is always thicker and needs more grinding. ON a flat stone you can do what is needed accordingly.. ON teh circular stone machine, I suppose there is a way to do this?
Whilst you are at it, Have fun. I used mine for a week adn that was teh end of it..WLd only give it to someone I do not like.
