Thread: DMT 325 aka The Wonder Tool.

I have never tried an Atoma due to the cost. I will love to get one though or a Shapton lapping plate.

I got one (DMT 325) to lap my first hone, a new Naniwa 12k. Got the DMT 325 on the advice of gssixgun and others. After watching Lynn's videos and trying the lapping, I didn't find the sticking to be too much of a problem, but I have big hands and lapped under running water. It worked terrifically. I'm impressed with DMT's products and in fact got one of their Diamond knife steels for my kitchen knives.

Of course, I know nothing about Atomas

I'm really happy with my DMT D8C 325, I bought it second hand several years ago and I get the feeling the 325 grit rating is long gone. It's great for knives and tools too.

I have both DMT & Atoma. I use the DMT more often because of its size (10x4), its easier to use and the finer grit gives me the surface I want. The Atoma works faster and I like the diamond clusters. The clusters and the way they cut is a great idea. When I profile a stone I'll finish with the Atoma, its a great tool if you have the need for it. If you just need a quality stone lapper the DMT would be my choice. The back side of either has great uses also.
