Thanks for the offer miso2, but I guess I will "let it go".... I love my Rockstead's and don't want to come off as taking shots at them or questioning their integrity, quality control, etc. That was never my intent, I was genuinely puzzled by the numbering vs the date and how to know how a knife I own personally fit's into the overall production history. I can't think of another example where a serial number 449 was sold three years after a serial 519 (cars, guns, knives, etc.. anything with a serial type numbering system basically)
