Pure as the driven snow.  This is a completely flawless and homogeneous Select grade "La Grise" Belgian coticule whetstone, and its surface has been shaped to become an ellipse of 6.5' diameter down the 7" length, and a 25' diameter across the 2" width.  Impart an impressively concave bevel form on your razors and fine knives!

An inverse shaped slurry stone is also included, but it is not 'La Grise'.
