Does the Buck-184 come with the box and papers? Can you describe it based off the info posted at

You might also post pics of your knife as if you have an unusual version there are a few people here that I am sure would make you and offer you can not refuse. You might also be wise to look at what these sell for on EBAY as frankly some people pay more for knives on EBAY then you will ever see these knives sell anywhere else.
As for the other knife, that I can not help you with.
