1000/3000 grit from Naniwa During the sharpening process its generally the 400 grit stone that does all of the hard work while the 1000 and 3000 grit stones cops less of a beating. This combo stone makes a good companion for a 400 grit Kaiden Ceramic or Naniwa PRO as a complete and very effective sharpening kit. Naniwa Advance Sharpening Stones This series of sharpening stones from Naniwa are made from the same high quality grit as the Chosera series but made from a softer resin with slightly less grit for those on a budget. These stones are made from tightly packed resin bonded grit and have the following advantages: No pre soaking required - simply splash some water on the surface and start sharpening Faster cutting than regular stones Longer lasting - about twice as long as regular stones Much less mess than “cement” type stones The Naniwa Advance Stone series ranges from 220 to 12000 grit and are all made via the same resin bonded process to give a consistent “feel” through the sharpening process N.B. Please do not soak this stone for long periods as it will degrade the stone. Also these stones have no plastic base like our previous series but you can purchase a sturdy rubber base here. Dimensions: 210mm (L) x 70mm (W) x 20mm (H) - stone dimension
