Us Camillus Combat Knife. I was issued this knife in basic training in the army in 1977. The knife was in a crate of equipment that was in storage in the supply room after being brought back from vietnam during the pull out. These were given to us after taken off our TOE roster. I have only used a sharpening stone on it. Still keeps an edge and is sharp!. I put velcro on the back of the sheath to help hole it in place when I had it on my web gear shoulder strap. Free shipping! . Thanks....
