Many years ago I went to the Smithsonian Institution to see among other things the stuff that the astronauts took to the moon. I was intrigued by the stainless steel white handled machete which was used to ? split open coconuts on the moon? They said that it cost $1,000,000 per pound to send stuff to the moon. The knife looked to be about one pound. I don't suppose that they got a million bucks worth of use out of that blade.
