Great thread everyone. Tstaut, your knives are very unusual. I suspect the fruit knife is American made and the blade material coin silver rather than sterling. The hinges and lock appear silver plated. The base metal is showing through.
Here's a souvenir for the 1904 world's fair. The scales are cast aluminium which was very quite valuable material at the time.

Very true. In fact, the tip of the Washington Monument was made of aluminum for that reason. Here's an article on it:http://www.tms.org/pubs/journals/jom/9511/binczewski-9511.html
