- verified customerThe Dia-Sharp Extra Coarse is a good, solid lapping plate for my stones. However, there are several large size grains that continue to dig deep grooves when I lap. Also, a postage-sized part of one corner seems to have received less of the abrasive and is nearly smooth. Other than that, it is capable of rapidly bringing Naniwa and Bester stones back to flat and leave some mud for the next blade.
