Thanks Olivia.

I know what each sharpening medium can do, scratch wise. I am tryng to find out if the way these stones scratch is more beneficial to getting a better edge/shave. I had though about equal number of strokes, but I think there will be differences between the blades that will require each knife to just be sharpened with a different number of strokes. I don't want one medium to get a "lesser" mark because it may scratch slower than another.

The Scotland stone on your site is so beautiful BTW.
