The whetstoneshould be soaked in cold water for 10 minutes before use. During sharpening, regularly sprinkle water on the surface to maintain abrasive efficiency. By maintaining a constant angle of 15 to 20°(15° for Japanese knives, 20° for European knives), you will achieve a consistent edge along the entire length of the blade.

The stone flattener(sold separately) allows you to flatten the stone's surface when it becomes hollowed after intensive use, thus extending its lifespan. The sharpening guide(sold separately) automatically maintains the ideal angle, perfect for beginners. The wooden base(sold separately) stabilizes the stone on the work surface during sharpening.
