They should make a knife's edge a molecule sharp, just like in Batman Beyond.
That was the shit.
That's easy, use a flint or obsidian knife that has been properly made. Yes, they're far sharper than ANY modern knife, but fragile.
I carry a Buck Odyssey and my new Buck Rush (it's assisted opening, very nice machining as well).
Ceramic knives are extremely durable for being made of a poreceline like material, but they will break if used to pry, chip on the edge if used too harsh, and cn chip if dropped. The really good ones are made pretty well where they don't have such issues...
You can cut glass with em as well, but it will dull em. For most things, the edge isn't gonna miss a beat and it won't need to be sharpened (as it's hard as hell).
To answer the question of how they're sharpened, it's done the same way diamonds are cut, with diamond dust impregnated surfaces.
Out of my price range and too fragile for me though...
