Micro Fine ceramic stones: my first impressions

[Todd Simpson]

The issue with a ceramic or diamond plate is that the performance will depend on the surface condition. Unlike a water stone, where we can repeatably expose a new surface by lapping.

As one example, I have a DMT325 plate that is only used on steel and as a result the diamonds are very smooth and uniform – it produces a polished bevel and keen edge. I also have an Atoma 400 that is only used for lapping my waterstones and the diamonds are comparably rough – it produces an ugly bevel with no keenness.

Although I like the idea of long-lasting non-dishing hones, I don’t see an obvious way to fit them into a progression.

Todd, I have been arguing that in a related discussion: https://knife.wickededgeusa.com/forum/2-welcome-mat/13423-getting-a-mirror-finish-on-your-edge?start=30

Would you would be willing to describe your experience with ceramic hones there?

Incidentally have you directly compared the result of the 1000 diamond plate and the “1.4 micron” ceramic?

No,I have not carried out any experiments to compare them. But I wouldn’t be suprised if their abrasive performance (whatever that may be) was pretty similar.

I agree with this. Since my edges are for practicality and not aesthetics, I find that the diamond stones are more than suitable to 1000. Anything over that is time better spent elsewhere YMMV
