I use the edge pro apex....A quick lerning curve(doing some knifes for family and friends) Puts a great edge on my setup. But its a prodject to setup and to clean when you are done. If i just wanna maintain an edge on my cheap knifes i use an Chefs choice kinda sharpener. No cleaning and i pull it from the drawer and a few strokes and back into the drawer. But then again you dont get the razor affect witch all Kitchen nerds is worth.
