Item is relisted as "NASA ISSUE'' knife.

Seller now states, "my reading & input I have received from Randall collectors tells me that the blade is a Solingen blade and that this knife is one of twenty that Randall supplied to NASA in the early 1960s for the Mercury Program [!!]"

I don't know where he was reading, but if it was here he has misinterpreted what he read, because it has been stated clearly that this is probably not one of the original 20 knives sent to NASA for survival training in Arizona. If it is not Rhodium plated (which it doesn't appear to be from the close up photo of the etching) then it is most likely not one of the 20 NASA "survival" knives.

Edited to add:

Without examining the knife in hand, it is difficult to be 100% either way.
