Fast delivery, lateral labeling where that grain is. The stone fits well in the rubber frame and also does not slide right away. Inserted 10 minutes in water and off you go. Manual can omit it, the better you can view on YouTube. Importantly, the stone should grinding always have a slight film of water on the surface, so every now and drizzle in between a few drops of water on it. Although the grinding takes some practice but my Zwilling knife after 3 years of use, again focused properly.
