Thanks for the replies. The three pictures are just different views of these two things.
Here are a few more details.
When these devices are closed (the handles are together) the opening is roughly 1.25 - 1.5 inches in diameter.
The edges of the opening, when closed is beveled, as if it can be, or has been sharpened slightly.
Neither one is very sharp but could easily take a chunk out of the flesh of most large fruits or vegetables.
When fully closed, the one with the wooden handles in more nearly a circle; the other is more elliptical.
They are app. 4.5 - 5 inches long when closed.
Steve, I can't say if they are used in food preparation or not. I am hoping that someone here will be able to shed some light on what their purpose is.
It is quite the mystery, but I reckon I will survive not knowing what they are.
