My understanding:
The "SF" serialized knives are the issued ones to the new graduates.
The non-sf serialized knives are the ones sold in book-store to the OLD FOGs that have proof of having earned the their MOS's, prior to the 18x series..
It had to do with keeping the sequence numbers separate, yet still accountable..
