You can get the convex shape with the strop and compound or mouse pad and sandpaper, or you can get it reprofiled on a slack belt grinder. Generally, a good convex edge will start higher up on the blade than a V grind bevel, but not necessarily. If you are happy with the edge you are getting with your Arkansas stone, I wouldn't worry about it. Sharp is sharp. The curved convex shape is a bit stronger than a flat grind at the same average angle. To get the full benefit of the convex edge, it is a full or nearly full convex grind, where the edge curves from near the spine all the way to the final edge. This is not practical in most cases. Some knives are made that way, like the new Busse NMSFNO LE and the Bark River Golok. These knives tend to be outstanding choppers.
