I recently bought a manix 2 xl from the forums. He says he bought it from amazon and he does not have the box. I take his word for it, but there is an issue with the knife. I have looked at videos and pictures of the knife, and the plastic thing to disengage the lock is usually clear. Mine, however, is black. Did original owner mod it? I highly doubt this because the plastic thing is exactly like my "small" manix 2, except it is black. Is this a factor error? Maybe Spyderco made a couple of these?
