Sharpening stone with #3000 granulation is to be used for fine sharpening and removing the burr, or as a mid-step between #1000 and #8000 grit. This stone will leave a slightly toothy edge, so it is suitable for knives that will primarily cut vegetables, and for butcher's knives. The Naniwa whetstone from the Super* series enables fast and efficient sharpening of Japanese knives. This is a splash-and-go stone, so it is not necessary to soak it before sharpening, just splash some water on the top side of the stone and start. For easier sharpening, we recommend purchasing a Stone Holder (Sink Bridge) to ensure mess-free and a stable position of the stone during sharpening. Specifications: Grit: #3000 Dimensions: 210 x 70 x 20mm Stone series: Super Stone Model: S2-430 *Sidenote: Due to market expansion, Naniwa often changes the product name and its packaging - the Naniwa Super stone is the same stone as the Naniwa Advanced stone, with the same composition and characteristics.
