Naniwa - Chosera 800 and 1000 Grit Waterstones Pack
These stones are very popular with sharpening enthusiasts.
The Chosera stones by Naniwa are the best, fastest cutting waterstones on the market. The action of the stone on the blade is smooth and consistent, giving you excellent feedback while you work. They are relatively expensive, due to the large amount of abrasive in the stones, the magnesia binder, and the post manufacturing conditioning for stability. The 800 and 1000 grit combination is perfect for refining the edge after finishing with the 600 grit diamond stone. The pack comes with 2 stones of each grit.
