I was a little disappointed when unpacking because 80 grit is coarse but than I thought. But I could face grinding, the removal is enormous and the part is not for nothing called Coarse with this stone my old station wagon grindstone 250/1000 again. As written, vorzuschleifen not for every day, but to knives or just grindstones again plan to get first choice. And it is big enough anyway.
