I think Chuck was born with an engraver in his hand, can't imagine how many knives he has signed. This question has come up here before, my memory is that the response was 50/50. Personally, I think the more valuable or rare the knife, the more the Signature devalues it. I've seen a number of older early Buck knives he has signed. Yes, going to an event and meeting a member of the Buck family while they signed a (hopefully new) knife for you is your memory, it becomes your keepsake of the event, not mine. Myself, I would have asked for the signature on the box. I'm a collector but the presence of a signature is generally a pass for me. Anyone remember the 800 "Signature Series"? Yea, I know they are called the Signature Series because they are signed, beautiful knives with mirror polished blades and 3 signatures all over one side, ugh. I keep wishing I could find a set of those without the signatures. Don't even get me started on Buck's current practice of laser etching "Limited Edition" on everything, it is cheap and cheesy in a Smoky Mountainish kind of way, double ugh.
WOW, I just realized I got suckered into a thirteen year old thread resurrected from he dead...
