For best results, we recommend the use of stones with high grit size (>2000#) to ensure maximum sharpness. With these four diamond sharpening stones you can re-sharpen the blade of blunt knives (800#), give them a good sharpness (1500#, 2000#) and polish them with the stone 3000# for razor sharpness.
This package contains additional diamond sharpening stones for the Iki Ruixin Pro™ knife sharpener.
Grit sizes: 800#, 1500#, 2000#, 3000#
