The Gransfors Bruk Ceramic Sharpening Stone 4034:
The Gransfors Sharpening Stone is comprised of ceramic abrasive with a grain structure developed to best supply the needs of coarse and fine grinding.
The coarse, 180-grit side is used for repairing damage from hard wear, whereas the finer, 600-grit side is used for fine grinding.
The grain structure of the stone makes it both tough and long-lasting.
Unlike a natural stone, a ceramic sharpening stone can have a more precise grain size.
The stone has a round, flattened shape with beveled edges to give a rounded transition.
The fine side makes up 2/3 of the thickness, as this is the side that usually wears the most.
The stone is typically used with water but can also be used dry.
The Sharpening stone includes a rubber case.
