The Coticule stone is a natural whetstone with a rich history. The quarrying and production of Coticule in the Belgian Ardennes goes back to the 17th century. It is a sedimentary rock formed 480 million years ago from greyish-yellow volcanic ash and clay containing hard garnet crystals. These give the Coticule its exceptional sharpening properties.
Your straight razor will thank you with a sharpness like never before.
