Im not upset, I got a number of good stones, and i'll put them all to use no doubt. Just means I'm still on the hunt for a Escher oh well just means more fun times finding one!. Thank you all for the help I believe they are lower grit stones i'll figure them out as i play with them can always use them for setting bevels, or in my progression in some way I'm sure. Who knows one of them may become very useful in time. The more stones i get to play with the more i will learn.
