Skunk, do you always wear tactical clothing? You're scaring me dude - lol
Ruger - the one with the leather stacked handle is precisely like the one used in WWII, although if you don't have USMC stamped on it, it's probably a Navy or Army KA-BAR, they used them too actually. I forgot that I have a Navy KA-BAR that belonged to my uncle in Vietnam, it went through a house fire so it's not so pretty anymore, but I've got it all cleaned up and sharpened. There is a new KA-BAR for the Marine Corps but it's obviously not a 1943 issue - lol - high tech polymer handle, kydex sheath, bell and whistles, etc.
