I agree that polishing / buffing is the way to make it slicker long-term.
How long would wax stay on the blade during actual use? Specifically, stay on the part of the blade that makes contact with the wood? A few strokes, maybe a dozen chops max, I'd guess.
Now for a competitive lumberjack that is trying to chop through a 12" diameter log half a second faster than any other lumberjack entering the competition that day, then waxing might make a difference. Even if the wax only lasts for a dozen chops, if he finishes those 12 chops faster and easier than his competitors, he'll be in the lead.
