Notable how lo-o-ng those hilts/cross guards are. Maybe because the astronauts would be wearing gloves.

Were either of these three knives rhodium plated?

Recall discussion on another thread about the plating.

Back when I worked with metallurgists etc., they talked about different plating methods. The flash coating of copper stuck to car bumpers etc. better than nickel or chromium did, and the nickel or chromium stuck to the copper very well.

The exception was hard chrome plating, which put chrome directly onto prepared steel surfaces, as in when they told the DoD how to fix the M16.

But one cautioned me when I said I wanted to hard chrome a 1911, that in small parts hard chroming might cause what they called hydrogen embrittlement and if it did it could cause cracks in the part.
