Wow, this is your 1st ever post in four years - cool! I think I know what you're talking about when you say "fade spots", but pics would be great if possible. A lot of guys are going to say stuff like 'if the spots make you feel unsatisfied with your purchase, then yes...if they don't bother you & the knife seems otherwise solid, then no'. And really, that's my 3-cents as well. I'm assuming you didn't suffer a huge wallet dent for a CFK knife, & that you did some research & are aware of at least some of the CFK threads here on BF?
I'd love to see a pic of the knife, just to see the knife really, as the CFK designs can vary widely - at any rate brother, I hope you end up happy with this knife/situation.
