I recently got a vintage Imperial Eagle razor and honed it myself and I noticed that it has really soft steel. It sharpened up real quick and much faster than any other razor I've honed. And when I shaved with it the first time, I noticed that the first pass was okay but already by the second I could tell it was dulling. By the third, on my ATG pass, it was pulling bad and I had to switch razors. What gives?
