This seems to be the best place to ask this....

Daughter and I went to a Flea Market today. Lots of antiques, besides me I mean.
At one table there were a lot of what the man said were 18th century tools.

There was one interesting one that was held and opened/closed by scissor type handles. At the opposite end instead of the scissor blades were half balls. When closed the half balls would form a complete solid ball.

The man had no idea what they were for. He said some one had thought they were used by vets to hold a cows tongue so it could be given medication.

I'm hoping someone might identify what they are.
