Now, THAT one I know well, could be ordered through supply, and many many own them. I actually just passed on buying an older one, had talked to a pal who wore his out as a crew chief and who sent back to Charles for the spa treatment. Good knife, as far as autos go, and back 20-25yrs ago mostly a black market "psst, wanna buy a SEAL auto?" thing. Charles sells to military, while only civilians who can buy one are cops (who ARE civilian, contrary to their wishes to be thought a branch of military).

A great and detailed article, down a post or two..
