There is no easier, quicker way to sharpen them than with a belt sander. Even some cheap one will do a terrific job. Belts are cheap and come in multiple grits which are easily changed. I am a finish carpenter and my job requires me to use equipment so sharp that I can shave the end of the hardest wood. I'm not talking along the grain but against it. That's razor shape. Until you've seen something that sharp you really don't know what it is. A belt sander can do that with a head and it requires little skill and work. I'm sure that's the way the manufacturer does it. Just a more dedicated machine.
