Naniwa #220 grit stone is used for coarse sharpening of damaged or totally blunt blades, as well as for thinning the blade. It can also work as a substitute for a Flattening stone. This stone is part of Naniwa’s Traditional (their economy) line of sharpening stones.
Sharpening stone (whetstone) from Japanese producer Naniwa enables fast and efficient sharpening of Japanese knives. The stone is made of aluminum oxide and is considered to be one of the harder and rougher stones that hold their shape well and are slow to wear out.
The main difference between the Traditional and Sharpening/Super Stone series is the soaking time – we soak the Traditional line stones in water for about 20-30 minutes before sharpening. All their other series are splash-and-go stones.
The advantage of sharpening with a whetstone is that by using the correct techniques, we can achieve a remarkable sharpness of the blade. However, it is necessary to learn the correct technique.
For easier sharpening, we recommend purchasing a Stone Holder (Sink Bridge) to ensure mess-free and a stable position of the stone during sharpening.
