I got a moderately prices diamond parting tool from Penn State Industries. Up until now I have never tried to sharpen it but rather rub both edges on sandpaper lying flat on a workbench. When I hear diamond I think of something harder than a grinding wheel. Does anyone know how they make diamond parting tools (micro diamonds in the steel I assume) and if how they are made makes any difference on sharpening them? Thanks and Happy New Year
