The must be a continuity of the durability of edges all the way from dull to wire edge. It's the application that determines when the edge is too weak. A wire edge is just the extreme where the edge is too weak for anything. After all you wouldn't get that burr on the butcher knife if all you did was shave with it (assuming it was sharp enough).
I've never thought of the condition that requires stropping as a burr, although I could be wrong (it could be a microscopic one). I've visualized it as a condition where the microserrations are bent so as to spread out rather than the edge being bent. They do come back most of the way within a day. Stropping just pushes them the rest of the way. Also, I've always visualized the bending of the teeth, after they return, as being elastic. In other words, when you push them back, there's no fatigue. That would explain why you can strop and just refresh indefinitely. You're not breaking off teeth but jus sharpening the ones that are there.
