Recurve&convex?

[Mr. Wilson]

I can sharpen a convex edge using the mouse pad sand paper technique and sharpen a concave recurve with my rods but how do I sharpen an edge that is both convex and recurve like my fallkniven fisherman?

Thanks,

Mr. Wilson

Move the sandpaper on your mousepad until it's right against the edge of the pad. Strop against that edge.
