So I was working out a ding in another homemade near-wedge in O1 from my first try (4th of 4) and trying out some new hones... a Hideriyama suita, a Henckels 3/8 that was given to me by a friend, and my King 1200. I had a bear of a time lapping all these stones, and when I was done, my DMT 220 was almost bare of diamonds!

I'm not sure which stone was to blame... I think it was the King, but the suita stuck to the DMT pretty dramatically as well.

BTW, is the two-sided diamond hone with coloured sides (Dia-Sharp/Duo-Sharp) flat enough to use as a lapping stone? My local shops don't carry the DMT 325, which I should have purchased in the first place.
