Got the stone today and it didn't need lapping.
I took a Filli 14 that is not a looker, but an excellent shaver and ideal to compare the new edge. This blade had an excellent edge achieved by stropping to .1u on pasted balsa.
Cleaned the stone carefully and started with what I think is a 3 in 1 general purpose oil. It felt a bit thick and the feedback from the stone felt like it was gliding on the oil rather than cutting.
I changed to Balistol and it felt better. I still couldn't really feel the stone working and I checked for evidence that I am removing steel by cleaning on a clean paper towel. Only a slight discolouration of the residual oil was visible, but I kept going for about 300 X-stroke laps, waiting for the suction to start, but I didn't achieve it.
I did a tree topping test and it was clear that it is not as sharp as it was when I started, but decided give it a chance. Stropped for a 100 laps on clean hanging leather.
I made sure my trusty Feather SS was on hand and started my shave. Well what a surprise!
It's a completely different feel. Soft on the face, but definitely sharp enough to remove the whiskers without any fuss. End result was on par with any of the pasted edges and almost no feedback from the alum block.
Very impressed, so far.
Next experiment will be to take the edge back to 8k, 12k then the Yellow Lake and see if I can replicate the edge.
Thank you guys for the advice!
