I have seen only two used Emerson's.
One was a Raven I traded in myself, but probably should have kept. It was in good condition, aside from a good sharpening job, but I was bored with it at the time and wanted something else. I forget how much I got for it, I think about $60. I don't know what it sold for, but it was a dealer that doesn't mark up used knives very much, so $85 is probably tops.
I saw another of the same model priced at only $35. It was VERY used. Scrapes and gouges all over, probably multiple sharpening jobs because the edge had taken on a different shape.
Unfortunately I haven't seen any used Mini Commanders, which is what I really want. They seem too expensive compared to a mini CQC7 with the same general construction.
