Opinel carbon steel is awesome in terms of being easy to sharpen and edge retention, but it'll rust before your eyes if you get it wet. Agree about stainless blades. I've found them hard to sharpen.
Back to the OP, everyone has their preferred method of sharpening. It gets like a religious argument at times. There's quite a few threads on the subject. Having tried most methods, I like the Warthog sharpeners. Good results, easy to use and reasonable price.
