I just picked up a beautiful old Sheffield razor that has absolutely no bevel, and no edge. In fact, I think it may have been a theatrical razor-nothing sharp, no one in the play gets hurt. I'm guessing the edge was actually ground off at some point. Anyway, anyone have any ideas how to approach this? I mean is there anything different in the honing approach because there is nothing? I'm assuming I just start with the aggressive pyramid and go from there.
