>>167484ah, that one looks like the original AESK knife.
the one i posted is a Ka-Bar made USN Mark 1 remake. Here it is seen alongside the better known Mark 2 pattern (aka "THE" Ka-Bar)
I think Bokker makes a version of the Mark 1 as well. I have an original that my great Grandfather had in WWII, so i figured it would be a nice knife.
