Atoma Diamond plates work really well for lapping stones and doing bevel setting as well as repair work on your knives or razors.
Diamonds are arranged in a dot pattern rather than a continuous surface, there is less tendency for them to 'stick' to the stones when lapping.
Also useful for lapping abrasion resistant steels and doing initial bevel setting and changing bevel angles, on tools.
