I've got a DMT 325 that has served me well. Still does a great job on softer stones, but it has lost a step in cutting power. Not as a replacement, as there is still life in the Dia-Sharp. but I'm thinking of adding an Atoma 400.
So, for those that have used both, is the Atoma worth the extra money, and what advantages has it got, if any, over the DMT plates?
