I have 2 razors that after a couple shaves I put away and used others. They were honed by some of the best on this site and came to me super sharp. I pulled them out and stropped them and I just can't get them sharp again. I do have a 12k naniwa stone but haven't used it. Thought I could get by with just stropping them. The question is as they sit, do they build up an oxidized layer that ruins the edge and will require me to take them to the stone?
