Blue Whetstone

From Robert Herder, the maker of our knives, comes a Belgian blue whetstone.

Formed over 480 million years by a combination of pressure and heat, this whetstone is incredibly hard with a unique texture making it ideal for sharpening and polishing your knives.

Prior to use, moisten it with water and once finished rinse under water and place in a ventilated space out of direct sunlight to dry.

There will be natural colour and texture variations between stones but this does not effect its ability to sharpen.
