I just aquired a 21 with a birth date of Dec. 15, 2008. The handle code, however, is A 09, which I understand to mean the first quarter of 2009. The knife appears to be mint. December 2008 is very close to January 2009, which is in the first quarter of 2009, but it still seems weird that the birthdate precedes the handle code. Does it mean that it is a refurb or something else? What do you guys think?
