Thread: Lapping Norton 4K/8K to get rid of "Grainyness"

The white side needs to be smooth ti use or it will chip the edge of the razor and leave unsatisfactory results. You should be able to shave off the yellow side easily if you're done. I just did it this morning and I am smooth shaven.

Do not go to the yellow side until you are truly finished honing on the white side, it takes practice to know but a good indicator is if you see black building up quickly on the yellow side then you werent done on the white side and you need to go back.

Good luck!
