best way to sharpen a pocket knife?

[MikeWaters]

Those metal sharpening rods that chefs use--are they good for pocket knives?

How do they compare to sharpening stones.

I have a cheap carbide/ceramic device for sharpening.

Then you have all that diamond stuff.

It was much simpler when I was a boy scout.

Of course when the other boys were slaving over sharpening stones, I brought my parents sharpener that has metal discs you ran the blade over. I was done in two swipes.
