Hey Josh et al,

Have you worn out your coarse DMT yet? For me diamonds seem to not be forever. About 2" on one end of my DMT course (sic, but so many seem to be similarly spell-check affected) or 325 whatever seems to have lost its grit. I'm just curious if you, or anyone else, has had similar misfortune with their end-all and be-all smoother and lapper.

I've lapped my Chinese 12K and my Spiderco UF, among other stones and hones, and am wondering if the Spiderco may have stripped the diamonds as that one seemed to not want to be smoothed and trued, or if already smooth and true took umbrage with my efforts and in a moment of pique the lappee took it's resentments out on the lapper.
