Naniwa Super Stones

The Naniwa Super Stones are now called the Naniwa Advance Stones. Naniwa says they improved them by tightly controlling the grit sizes for more consistent and accurate cutting. These stones are resin-infused stones that are fast-cutting and silky smooth. Great for kitchen knives or razors. The Advance stones are splash-and-go and don't require soaking. Perma-soaking these stones is not recommended.
