Synthetic Nagura Stone from Naniwa
This handy little stone is used for a number of reasons. Before using harder compound stones rub the nagura over the surface of the host stone, it will speed up the sharpening process by activating the grit and binder in the host stone. Also some stones tend to glaze over very easily. In this case just rub the nagura over the surface to remove the embedded steel particles and to reveal a clean fresh layer of sharpening grit. If in your budget natural nagura are preferable as they generate a good slurry to make sharpening easier.
Pre soak the nagura for about 10 minutes before use.
We recommend this synthetic nagura for 400 and 1000 grit stones.
