Description

Belgian stone quarrying on the Ardennes mountain range is first mentioned in a document from Roman times. However, the history of the legendary natural sharpening stone goes back much further. The yellow-gray sedimentary rocks dating back about 480 million years are composed of volcanic ash and contain garnet crystals. During the sharpening process, the latter break away from the rock matrix and form an abrasive paste with water and abrasive. Garnets remove only fine metal shavings and provide fine polishing with good metal removal. This combination of speed and finesse is unique in the world.

Good to know: about 1,500 kg of rock needs to be extracted for the production of 1 kg of sharpening stones. Fine yellow layers are glued onto slate panels and cut into countertop stone or fragments.

Qualities of natural stones
Belgian stone and Arkansas stone have been synonymous for many years with excellent sharpening stones. However, in the case of these stones, they are natural products. Quality may vary all the time due to limited resources.
