The straight guide rod gives straight edges, the bended guide rod gives convex edges and the slightly curved fine diamond sharpener gives recurved edges. All in the same sharpening tool.
If you want to se them, look at my Swedish homepage.
Convex edges is nice to cut fresh meat, that is why I think that hunters knifes absolutely shall be convex. If you slaughter a mouse with a V-shaped knife you need to sharpen the edge during the slaughtering. You do not need that if the edge is convex. I think that tells a lot about the convex edge.
