DUO whetstone on bamboo
Thanks to its special properties, this whetstone sharpens kitchen knives particularly efficiently. Firstly, because it has two different sides. The blue side (240 grit) is used to restore dull or damaged knives, while the fine, white side with 1000 grit restores the perfect sharpness. Before use, soak it in lukewarm water for 5 minutes. When combined with water, tiny corundum particles form an abrasive paste, achieving exceptional sharpness.
