Well, from my years in the Corps I can say that I never saw a knife issued to a Marine.
A bayonet will be issued, but only for deployment or actual combat situations.
Never saw an issued K-Bar, anyone who had one bought it themselves.
Personally, I bought a K-Bar after boot camp, and would also carry to the field a Spyderco rescue (when they came out) and a SAK or Leatherman or some kind of smaller pocket carry knife.
They aren't too keen on giving everyone a lethal weapon when there isn't an enemy to use it on. Heck they had enough trouble with guys getting drunk and beating on each other with bare fists. (actually saw a guy get stabbed at the E-Club in Panama)
In fact regulations stated you couldn't have a knife with a blade over 3 inches in length...ON BASE...PERIOD....
If it was, you had to check it into the armory.
As far as survival gear issued to your basic ground pounder, all that was issued was a very basic first aid kit, water purification tablets and not much else.
