I found this on a date with my wife. She talked me into going to an antique store with her.
I'm posting because I would like a bit more info on it. I have always liked the look of this style but never owned one. First off, what do you call it? I saw some switch blades with similar profile called "humpbacks," but that also refers to a completely different style, the humpback whittler, etc.
So what do you call it?
Also I don't know much about Ulster. I think this is pre schrade, the tang stamp says Ulster knife co, ellensville, ny.
I could not find a tang stamp chart for Ulster.
