I wasn't sure if A was 2000 or 2001. Thanks for the clarification.F is the month (June) and Q is th year (2017).
Month , A = January
Year , A = 2001
Regarding Spyderco Date Codes: I understand the two letter codes; however on the Spyderco Efficient Brown I just received must have a different code?? You have the usual bar code with the number 7 outside the bar code to the left and the number 4 outside the bar code to the right?? Has anything changed......the bar code is: 1610401237 with the additional numbers outside the code...?
So datecode "CS" means March 2019, yes?
