Belgian Coticule and Whetstones

About Our Belgian Coticule and Whetstones:

The Belgian Coticule is a naturally formed, premium sharpening stone that has been extracted in the Belgian Ardennes since the 17th century. The Belgian Blue Whetstone, or BBW for short, is extracted together with and at the same location as these Coticules. Occasionally, naturally formed Coticule/BBW combinations will occur, as the Coticule layer has remained attached by nature to the BBW layer; but, whether they are found together or alone, both make truly formidable sharpening stones!

The Select Grade Yellow Coticule features a layer of yellow coticule stone, and a base made of Belgian Blue Whetstone; sporadically, these naturally formed Coticule/BBW combinations will occur, and are able to be extracted as a single stone. Both sides of these stones can be used to hone, and each feature their own distinct grit rating (8000 on the Coticule side, and 3000 on the BBW), making them a particularly useful addition to any stone collection. 

The Standard Grade Yellow Coticule features a layer of yellow coticule stone and, unlike their select grade counterpart, do not have a Belgian Blue layer; instead, each of these sharpening stones have been glued to a a slate base for added strength. Remember, only the coticule side of this stone can be used for honing. Each of these stones has a grit comparable to that of a 8000 grit whetstone, using the Japanese grit system. 

The Belgian Blue Whetstone features only a single layer of the Belgian Blue stone and, unlike either of the Coticules, comes without a substrate to give it extra strength, as it is unnecessary with this particular stone. Each of these stones has a grit comparable to that of a 3000 grit whetstone, using the Japanese grit system.
