They've sure wasted a lot of advertising money in the knife magazines. Been doing so monthly for maybe 2 years. Weird.
Sorry, I've thought several times about buying one, but never have. I have bought a couple of the little sharpeners with the crossed tiny ceramic rods. I doubt they remove as much steel as the turning wheel design, and don't sharpen very quickly, but they do add some sharpness after a bit of work. I like the concept because I don't have to try to remember which side I just did.
Also, I find the Gatco TriSeps (sp?) to be pretty effective. It is a short -- 3-3.5" -- ceramic rod. Probably not super useful for a big fixed blade, but it does work well for me. It also has the little groove for sharpening darts and fish hooks. The plastic caps on the end enable one to hold the rod at different angles, then keep the blade perpendicular when drawing down the length of the rod.
