Ardennes Coticule, sharpening with a natural product

The Belgian whetstones from Ardennes Coticule are found in the Belgian Ardennes since 1625. The whetstones from Ardennes Coticule are also known as Belgian chunks, named after the chunks of stone required for the production of the Coticule and the Belgian blue whetstone. Both products are real natural products with a labour-intensive mining process.
