For a water grinding wheel, you must soak the stone under water for at least 45 minutes.

But that does not mean that you can just choose the grinding wheel with the highest grit, but also based on the type of knife that is being sharpened because his father has a saying “pot upside down”, applies to the grinding wheel and The knife is also very suitable.
