The trip sounds nice. I hope you have a great, but socially distant, time.
Newest hone, huh... I would think that it could lap a few stones and still be fine, but Arkies are really hard. I haven't tried diamond plates for honing. I have an Atoma #140 for lapping stones. ... I would think the DMT 1200 would be decent for bevel setting. ... Weird. I am glad that you got good results from the paper, however. There does seem to be lots of trial and error when it comes to finding a honing setup that works repeatably.
