In Basic, your knives will be banned. If the Corps wants you to have anything during basic, they will issue it to you. This includes the air you breathe. About the only thing they won't put a clamp on is your Bible and address book.
After basic, the knife you carry in the "field" will depend on about 300 different factors including, but not limited to, your MOS, your commanding officer or NCO, your supply Seargeant, the idiots who stabbed themselves in the foot the week before you go there, the terrain you will be in, and the phase of the moon.
What you can carry while in Class A's will vary from what you can carry while in BDU's. And what you carry in uniform may not be legal for you to carry in your civies. (Oddly enough, the opposite may apply also.)
No one said the Military made sense.
Semper Gumbi - Always flexible
PS - They will issue you a big clunky thing called an M9 (not the Beretta version either!). You will do just about everything with it except use the edge of it.
