Made in Japan by Naniwa, a renowned maker of premium sharpening stones favoured by professional chefs, this 1000-grit whetstone is designed for restoring and maintaining the edge of Japanese knives.

Ideal for slightly dull or moderately damaged blades, the medium-coarse grit delivers a smooth yet effective sharpening action, leaving the knife sharp enough for everyday use.

To create a razor-sharp finished edge, a finer whetstone such as the 3000/6000 grit combination whetstone will be required.

Before use, the stone should be thoroughly soaked in water. This activates the sharpening surface and provides natural lubrication, helping to reduce friction and prevent overheating during sharpening.
