Dianova Lapstone knife & axe sharpeners are Swedish-made quality diamond sharpeners that will easily keep knives, axes or other tools sharp.

The great benefit of a diamond sharpener compared with a conventional honing stone is that it can be used dry, it maintains its flat surface throughout its lifetime and it reduces the grinding time substantially.
 

If used dry it should be washed regularly. Instructions included. Dimensions: 12.5cm in total, diamond surfaces are 7.5 x 2cm Included with the classic short sharpener - a black nylon pouch.
