Gene,
Thanks for posting the original fish pic, it kinda adds to the Nautical theme of the Mariner.
As for the black mariner. I picked it up since it seemed odd. It is the original no vent, MARINER on blade, unchamfered version but somewhere along the line it was coated.
I don't think Spyderco contracted out for the coating that early, however, John F. Jensen was doing the coatings for Spyderco and I suspect it may have been done by him sometime later on.
Maybe someone else can add to the story.
