Here is my Real Steel Bushcraft Plus/14C28N with convex edge.
I figured a simple way to keep my Real Steel secure in the sheath and still have quick access to it.
I wrapped a black shoe string around the sheath and then left enough on the end so I can plug the end into the hollow rivet on the handle.
Then, when I remove the knife, I can slip the end under the wrapped lace until I need to use it again
