Joe touched on everything I saw wrong. The dead giveaway is the "inclusive S" stamp, found on blades produced after 1969. That's really where the fakery lies. The sheath would be mismatched to a genuine tenite knife as well, the gold paracord would be found early 1970s. Using a good sheath with a faked up knife could trick the unsuspecting... it's a shame, and a sham!
