If we assume the flat bit on the short arm to be an anvil of sorts,
and the groove in the jaws are to hold a ferule, then it could be
a hand held, hammer struck crimper.

I think that we've now seen another tool that has a "nib".
Check out the left end of the long handle.

Not wanting to start the nib thing again of course!
