I've got a blade that maintain on .5 Crox, .25 CBN, and .1 FeOx. No linen or leather, just pasted strops.
The shave is a bit prickly, but not as much as I feared. And 1 pass is all I need to match a 2 pass shave with (most) any other razor. It's been an interesting little experiment. I need a better strop for my FeOx though, I think it could get much better with a higher quality linen/fabric.
