A fine-grained, clastic sedimentary rock, composed of mud that is a mix of flakes of clay minerals and tiny fragments (silt-sized particles) of other minerals, especially quartz. Shale is characterized by breaks along parallel layering or bedding less than one centimeter in thickness, called fissility. It is the most common sedimentary rock.

More properly, the stone is a type of Sedimentary Quartz (a term which Schoolcraft attempted to get coined as well but failed) formed into a microcrystalline matrix. Novcaulite in a geological sense would probably fall under the moniker of Chert, Flint, or rarely Quartzite. ... Analogous "Upper End Conditioned" Grit Rating – Fine Variety ...
The fine grit is all that is really needed IMO for a very nice, very sharp, slightly toothy edge. But if you want a more refined (smoother) edge there is no better choice than the UF stone. When I use the 8k Shapton glass stone after the UF stone I can feel a difference in the smoothness of the edge but only if I'm cutting something very ...
