Naniwa Bulge
The photo below is of a Naniwa 10k that has been lapped for just a few seconds with a DMT plate. What causes this bulge in the middle (that the DMT is shearing off)? I have lapped this stone before so after some honing use shouldn't it tend to show wear in the midle instead of a bulge?
