My sharpening technique: A polished edge that is coarse, best of both worlds

Next, I will try sharpening with water. I've seen how 10 million years of water have smoothed rocks in the river.

You'll need some sort of abrasive mixed in. I guess it would be possible to have a steady flow of water loaded with abrasives that could polish. You'd probably need some pressure and keeping the direction going over the bevel would probably be extremely difficult. Water kind runs where it wants after it comes out of a valve or hose. I guess if you directed the stream from spine to edge it'd be possible. They cut metal with water jets. But AFAIK it contains abrasives.
 
Yeah, waterjets setup to cut metals or harder all have an abrasive mixed in. The water didn't carve the stones, it eroded them the smoothing effect is from suspended particles as well as other rocks hitting each other.

I'm not stopping you from running water over your knife for hours, but you might try abrasives and a stream.
 
I have the best of both worlds on my Izula at the moment. First I polished the whole edge then took a DMT Fine (red) and sharpened the forward part of the blade beginning about a 1/4 inch past where the belly begins all the way to the tip :thumbup:

Did you know that frozen water at -400F is as hard as diamond?
