I had my first shave with a razor finished on an Imperia La Roccia and here are some observation.
First the honing, so far I have only tried to use the stone with no slurry and as a finisher, either after a Shapton 12K or a Shapton 16K. That particular stone was sold as 12-15K and that does not look to be accurate if considering a Naniwa/King scale but it is not that far off.
The scratch marks are on par with both shapton, so I'd say they are a tad over 1 microns.
After 50 laps, all the marks from the previous stages were gone, I did not check with less strokes, so it might even have been faster than that.
I managed to get a nice HHT off that stone (after some stropping). The edge does not seem as polished as after an Agate treatment and the lines are bigger than crOx, but I refrained myself from doing anything after the Imperia to check the specific signature feel of the stone.
I tried it this morning and it worked on well. The LeGrelot #7 I used with it was very smooth. Not quite as sharp as after a gem or crOx finish, but sharp enough to do the job and it gave me the smooth shave I'd expect from that LeGrelot.
So in conclusion, the stone works.
Next I'll be trying to use it off the King 6K with a slurry to see if it can replace the need for a synthetic finishing stone.
I honed 2 more razors on that stone with different metal quality, so I'll see how it fared on the others as well.
