I use a Gatco sharpening system to sharpen my blades. Its similar to a Lansky, with a clamp and various stones with a rod/guide. That gets them shaving-sharp.

After using a blade, i try give it a wipe with an oil-soaked chamois. to touch up the edge, i use the gatco. if i'm on the move, i have a small Spyderco Pocket Stone.
