Japanese Water Stones....
First used them for my wood chisels. Sharpened the beveled edge at 25* with a Veritas Guide, till they were shiny as a mirror, then would do the back to clean up the factory grind....they are beyond sharp.
Started doing the same thing with my knives over 10 years ago, and boy are they scary sharp.
Like a rifle with a light trigger, you warn folks before you let them pick 'em up. If you try to shave with them, they won't only remove hair, they will remove any moles that stick up a bit from the skin. Think I'm kiddin? Try a water stone, and work up to 8000.
I can gut/skin/butcher two deer and not need a trip to the stone, just a touch up with the steel every once and a while.
I'd say it works great.....but hell, I ain't nobody.
