Hi all,

I have recently begin using an Atoma 400g diamond plate (fixed diamonds) to maintain a set of Sigma ceramic stones--1000g, 2000g, and 13000g. These stones cut quickly and also collect swarf quickly. I have found the Atoma plate very effective so far in truing, deswarfing, and regrading the stones.

I say 'so far', because it's still early going. Don't know what this diamond plate will be like in a year, whether it will stand up to continued use, or abuse as I subject it to sharpening uses in addition to stone grading.

I like the Atoma 400 a lot so far.

Questions:

1. Anyone else using this plate? Any experience or suggestions to offer?

2. Do you folks using Arkansas stones grade them with diamond or other abrasives? Do they benefit from surface regrading?
