I just yanked out a few eyebrow hairs and gave it a try. To my great surprise, some of my knives can slice shavings off of a hair, like in the video. My SS4 can do it. (Not quite as smoothly as the game warden in the video, but fairly close.) My Dumpster Mutt couldn't do it. My 6" PBF could do it, but not nearly as well as the GW in the video.
Perhaps tomorrow I'll get out more knives, get out the strop, yank out more eyebrow hairs, and experiment some more.
