Pliny (a Roman scholar from 23-79 AD) already mentioned special whetstones from the Ardennes in his writings. In this approximately 480 million-year-old slate sedimentary rock made of volcanic ash and clay, the finest garnets (5-20 microns) are embedded in veins of 5-20 cm. The blue Belgian slate contains approximately 30% embedded garnets and has a grain size of 5000-6000. It is very easy to use. When used with water, it maintains and sharpens the cutting edges of knives and tools without leaving a burr. Natural stone, approx. 150 x 40 x 14 mm. Benchstone, grain size: 5000-6000.","brand":"Belgischer Brocken - Schleifstein Deluxe, Pfarrhofstr. 14, 94405 Landau an der Isar, Deutschland. info@belgischerbrocken.com.","offers":[{"title":"Default Title","offer_id":45815353966841,"sku":"920146","price":40.58,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0723\/3178\/8537\/files\/7925-20146.jpg?v=1754911727","url":"https:\/\/gastro.stayspiced.com\/en\/products\/schleifstein-belgischer-brocken-naturstein-blau-15x4cm-kornung-5000er-1-st","provider":"Stayspiced-Gastro","version":"1.0","type":"link"}
