Sharpening Stone Fällkniven DC4, Diamond/ Ceramic

This sharpening stone from Fällkniven combines a side of fine diamond (25 micron fineness) and ceramic (synthetic sapphire). Due to the very hard materials, powder metallurgical steels can also be re-sharpened. It is recommended that the whetstone be cleaned occasionally with detergent and warm water. Oil is not necessary for use. The grinding stone has the following dimensions: 32 mm x 100 mm. With the FNDC3 a more compact version is also available (25 mm x 75 mm). It is delivered in a black leather case. NEW FROM NOVEMBER 2019: The back of the leather case now has a rough honing leather.
