A very handly little item to add to your care kit if you own carbon steel knives, the abrasive surface is used to remove any rust spots that can develop on reactive steels.
Available in 3 levels of abrasiveness - Fine, medium and rough. Please be careful when using, it is an abrasive so is capable of removing a kurouchi finish if you scrub too hard.
It can also be used on any household items that develop rust such as taps and pans too.
