Depends on the final angle of the edge and how convex it is. If the curve is large, you'll hit the shoulders above the edge. If the curve is shallow, you can use the Sharpmaker as long as the edge is equal to or lower than the standard 30 or 40 degree settings. You will not be able to polish the entire bevel, but the Sharpmaker is capable of adding a micro-bevel and sharpening the edge.
