A what-is-it question that I'm convinced will have you all beat!
A novelty that was patented in 1885:

I'm not too sure of the actual size of item, but I guess the illustration shows it somewhat larger, I suspect the size more likely to be around the image below, but don't hold me to it:

The illustration on the left shows the item in the open position, on the right, closed. It was initially only available in either gold and silver.
OK, what is it?
