Natural whetstone from the French Pyrenees
The stone must be soaked in water for about 10 minutes before each use.
As this is a natural stone, there is no defined grain size.
This stone does not require any particular maintenance. After a certain period of use and if necessary, you can clean the stone with a washing-up liquid by brushing it under hot water.
