Belgian coticule whetstone polygon – natural stone for sharpening by hand

The yellow belgian coticule whetstone polygon is a traditional grindstone from the Ardennes. The coticule or belgian coticule whetstone polygon is available in many different shapes. For starters, a single sharpening stone is often enough to keep your wooden tools sharp.

Natural sharpening stone from the Ardennes

Coticule has been mined in Belgium since the 17th century. It is a very old sedimentary rock made of volcanic ash, ash and clay, in which garnets are embedded, which make up around 30 to 45% of the natural stone and give it its sharpness. The narrow coticule layers are located between broad layers of slate and can only be quarried by hand, a labour-intensive process. This makes each stone unique.

Fast and fine sharpening with the Coticule

Due to the geometry of the embedded garnets, a belgian coticule whetstone polygon can be used for both very fast and very fine sharpening. At bildhau you will find natural sharpening stones with different profiles so that you can find the optimum stone for every wooden tool.
