Relationship between metal fatigue and stress hardening

[grepper]

What type of application are you wondering about? Are you wondering about a specific steel or instance?

While it may be more intellectually interesting than of practical consequence, or not, I don't know, but if you bend a burr back and forth during stropping to remove the burr, does that impart hardening to the edge of the blade?

Obviously the burr fatigues and fractures, but is that plastic deformation rapid enough to actually harden the edge?  Hence my previous question, "Practically, what period of deformation are we talking about with room temperature stainless steel to induce hardening?  1 per second?  Five/second?  1/month?"

If hardening does occur, to what depth?  Is it significant enough to improve edge retention?
