The CBN Wethulpstuk (Law language) is a steel plate with very fine CBN granules that leave a polished surface. Because of its ingeniously simple design for almost all chisels, the law language is an ideal tool to get rid of the grinding burr, no matter how small. The picture is 145 mm long and 47 mm wide. On one side there is a radius of 2.7 mm and a radius of 6 mm on the other side. As a result, all the guts on the inside are also laws. For the laws of flat chisels and the outer surface of the guts, you obviously use the flat part of the plate. An important advantage of the CBN grinding agents is that they are shape and have an unprecedented lifespan! A stone wears and changes form.
