Friends, thank you for the advice. I will try to make the photo even though I'm not sure what I can. I do not have a good camera. I try to write to the manufacturer, but I'm not sure that he will solve this problem, I do not want to send the stones to them, it will cost you. The surface of the stone was loose and the corners considerably whittle down, the stones were originally rough. They could not hurt during transport, they left such a plant. Unfortunately I do not know much English, and perhaps the translator did not translate privilno (( correctly )) some of my words. As a result, lost a sense of what I write. I've searched in Google and noticed that many people complain about the poor quality stones spyderco triangle. I want to try to align the stones on the sandpaper, maybe it would make them a little better.
