Jack, Thanks for posting the pictures, interesting knife, what are the thoughts here about this sheath and knife being original to each other? Does anybody notice that the top of the blade does not seem to be in direct line to the handle? Is that just lense distortion in the picture or could it have been rehandled? What color handles did the majority of the NASA knives have? What do you guys think about the texture, "grain" and color of this handle? Is the blade stainless or carbon? It sure looks spot free for carbon. Just a observation the sheath throat doesn's seem to have much wear for this vintage of piece, could it have been stored outside of the sheath for much of it's life? Regards,
