Not to sound facetious, but you sharpen your knife when it gets dull. It's really that simple.
As to hair popping sharp, I think that has as much to do with your hair's characteristics as it does with the quality of your edge. For example I have very fine body hair. I have never been able to get any blade to shave it, and that includes my straight razors. My facial hair on the other hand is understandably more coarse. I have no problem shaving it with my slipjoints.
I like my knives book push cutting sharp.
now that is sharp!
