I have a set of the small diamond cards. I use the fine, then the ultra-fine. Moisten with water, then face down, I go around in a big circle 50 times, then in the other direction 50 times. Then I go back and forth 50 times and back and forth the other way 50 times. Then I move to the ultra fine and repeat. Takes less than 10 minutes.

I agree the edge is not quite as good as new, but it certainly more than serviceable. I can usually get four or five blanks per edge on my R2 cutter before sharpening again. More if turning wood, less if turning finicky blanks like Acrylester. I've probably turned at least 100 pens on the cutter I'm using now.
