My Deregulators came in today. I wondered about the "numbered" knives and how they'd track who received what. I bought five Deregulators + sheaths, three of which were military discounted and two were not. My three numbers are 4671A, 4671B, and 4671C -- is that how it worked for other people who ordered multiples? Did people who ordered only one military discounted Regulator/Deregulator just get a 4-digit number, or was the knife ID pattern number+letter for everyone?
