They are 2 1/4" long. The only place that I have ordered from that had 2 1/4" blades only had the From blades. I have seen reference to Persona blades and another one that is a medical prep blade in SS. I think I have nothing to loose stropping this one to get some smoothness going on. It is built very much like straight so the mechanics should be the same. Perhaps I will use an older stop for this experiment.
