I prefer the chrome ox powder to al-ox for fine work, but the al-ox stick to the pure powder in the shop on the rare occasion that I'd use it (small knives, etc).

Only trouble with true graded chrome ox is that sometimes the suppliers who provide it for a reasonable price disappear.

I like what chrome ox pigment does to an edge (it's very smooth - gentle on razors ), and as much as I don't use it on my own razors, the market of buyers for razors seems to prefer that a seller make their razor shockingly sharp - so I do that.

I have gone to finishing my incannel gouges on a hard buff with 5 micron al-ox wax stick, though. It works well and is probably worth taking a microscope picture of - they are sharper off of that buff than they would be off of a trans slip. I keep them in shape almost entirely with a gray deburring wheel and the buff. The edge is drastically different (more refined) than it is when the wax is spread on a hard leather strop or MDF - the particle size is too large for that.
