Anyone here ever have the above hone? I just picked one up at an antique dealer for $ 7.50 in very good condition. No chips, or cracks. Its an unusual dark green color, and very long and very thin. It may have Chromium Oxide as a base, I don't know. It seems like it puts a better edge as a finisher than some of my other barber's hones leading me to believe in the Chromium aside from the color.
