I was just looking around a local gun store and saw he had an Emerson CQC-11 for sale. I asked him about it and he said its been sitting there a while and he gave me a great deal on it. Anyway I noticed its serial number is 0040. Before I put this knife to hard use, I wanted to check and see if it might be of more value to a collector. Is this knife worth more than sticker price or should I just put it to work?
