Are the issue knives for the Marine Corp still made by Ka-Bar or another brand? And do they issue them in leather or plastic sheaths.
The Marine Corps doesn't issue combat knives anymore except for the bayonet and folders. The bayonet is made by Ontario Knife Co. and is called the OKC3S. It comes with a kydex sheath from the factory. You usually get a choice of a Benchmade automatic folder or a Gerber Multitool when you deploy.
