Coticule Standard Bout 4: 27-33 cm²
The Coticule Selected consist of a Coticule top side of 7 to 10 mm and a bottom side of unusable black shist. The Coticule stone has between 6000 and 8000 grits and contains 30 to 42 % garnets, which results into the stone being very fast at whetting knives. The Coticule has a yellow-white colour with red and green shades from time to time. The Coticule Bout has irregular shapes, depending on how it is cut out of the rocks. There is no quality difference between the Selected and the bout, only the shapes differ. "Selected" provides a homogeneous stone while "Standard" shows cosmetic defects or natural colourisation.
