The Naniwa P-330 Professional (Chosera) #3000 Stone is Ryky’s all-time favorite whetstone. Period. If he had to pick one whetstone to use for the rest of his life, it would be this one. It’s fast cutting, responsive, and will give your knives a razor sharp, and well-polished edge. Ryky has chosen this whetstone as whetstone of the year for a few years running, and is still his go-to whetstone in his personal kitchen.
