I have the Sorby system with the fingernail and standard grind adapter. The problem I have with it is that there is just so much "play" in the components as to make for an inconsistent grind. I have tightened all the bits that can be tightened. It just doesnt seem to me that well made for the money. Does anyone else have a similar problem with it? I am considering selling it on and adopting a new system. I'd welcome people's views on it.
