The above is one I was looking to get a value on. Can't find anything on it. No ebay sales of that particular knife/sheath. Bought 2000ish.
Another id like to find is an old one that had a 22 hornet casing in the handle on. Single blade iirc. Maybe 2.5 inches. Im pretty sure I lost it through my coveralls inside pocket while feeding hay before school one day. Never saw another like it. It may be at my old house but I remember losing one (at least) through that stupid pass through pocket on my overalls. I have pretty much every knife I ever had since I never part with anything.
