MORE INFO
Extra-fine water stone. Universally applicable. 35 - 40 % garnets.
Traditional yellow stone with 35 - 40 % garnets. As this quality is rare and precious, it is cut from the rough stone in a polygonal shape (chunks) and cemented onto a layer of slate for stabilisation. Extra-fine quality.
Coticule is a natural stone and is usually composed of 30 to 45 % garnets, which are bound together by volcanic ash. Coticule owes its exceptional cutting properties to the garnet content.
The Belgian coticule whetstone polygon is a closed-pored stone, which is why it cannot clog. Only water is therefore used for sharpening, never oil. Oil is only used for porous stones to prevent the deposition of metal particles in the pores.
It is sufficient to moisten the surface of the Coticule - it should not be immersed in water. Grenades are exposed on the surface of the coticule during grinding and the moisture creates a kind of grinding paste.
If the profile of the grindstones does not exactly match your tools, you can simply adjust it to your requirements.
When sharpening carving tools with larger coticules, the stone can become uneven due to frequent use. To restore a flat surface for precise sanding results, you can dress the stone: To do this, place a piece of sandpaper on a flat surface. Add a little water and sand the surface of the coticule. Use sandpaper with a grit of around 80 to 100 micrometres. The flat surface of your Coticule is particularly important if you want to sharpen tools with a straight cutting edge, such as for example, a plane cutter, chisel or plane blades.You can find more information about Belgian coticule whetstone polygons and coticule sharpening stones in our expertise article Coticule - Belgian coticule.
