Ardennes Coticule Belgian Blue and La Pyrénéés combination sharpening stone 100x40mm

The Ardennes Coticule Belgian Blue & La Pyrénées 100×40 mm is a compact and efficient dual-sided natural whetstone made from two premium materials: Belgian Blue stone from the Ardennes and La Pyrénées stone from Southern France. With grit levels of approximately 1200 and 4000, this combination stone is ideal for both coarse sharpening and fine finishing.

Thanks to its compact size, this stone is perfect for sharpening smaller knives like traditional Nordic puukkos. For kitchen knives and wider blades, we recommend the larger 150×60 mm version for better working surface.

Its beautiful blue color and natural texture make it both an elegant and high-performing sharpening solution for knives and tools.
