I'm just wondering if anyone knows much about a 707 Uncle Henry or what it's worth? Stamped on the blade is "Schrade +" and "USA 707UH" I got a few USA Schrades from a lady I worked with, some in the box, some not. I can tell this 707 has never been used, but, I don't have the original box or papers with it. I've heard they are "rare", but, if so, how "rare" are they?
