Found this in a desk drawer in my house. It was my grandfather's that he used I don't know how many decades ago. I thought I would try it and got hooked. It is a 5/8 extra hollow ground by American Razor Company in New York. Not sure about their reputation.
I cleaned up the blade a ton once I decided to dedicate myself to using straights. You can still see quite a bit of tarnish and crap on the tang compared to the blade and shank. It's nothing terribly special other than it was my grandfather's. I think the scales are just plastic, and the pivot is a tiny bit loose. But overall it seems to shave pretty well for me.
