I'm tired of water stones. A long time ago I started working on a holder to keep the stone at a 22 degree angle so I could hold the knife vertically, which seemed like an easier angle to maintain. This is the basis of a lot of manual knife sharpening systems. I never got it done and I got frustrated this morning and just said screw it and ordered this Ken Onion sharpener. It supposed to be the bee's knees. Hope it works out.
