The Gerber was purchased in 1969 most likely at Ranger Joe's at Ft Benning. It went with me to RVN and never ever saw the top a a C-ration. I carried a M-16 bayonet as a work knife and it was one of the most worthless pieces of steel ever invented. Now the old M-1 bayonet which was about four feet long and could reach out there and gouge somebody at a respectable distance was a fine piece of hardware except for the rifle it was attached to was a little on the heavy side and slow on the cyclic rate.
