Mystery nippers?

Over a foot long, looks like a steel forging. Maybe for animal hoof clips?
Has an adjustable bite/mandible. Super great patina.

It's a laminate cutter, like the stuff you put on countertops. The double anvil keeps it from splitting the stuff (which is rather brittle).

That is a rather nice one, generally they are stamped sheet metal...

 I use them for cutting and crimping pipe such as stove pipe and guttering.

It might be useful in cutting laminates, and cutters for laminates may use the same pattern, but this is for cutting and re-crimping things like stove pipes and gutters, just like jimwrench wrote.

Stove pipe cutter and crimper. Used one many times in the hardware store cutting stove pipe.

Thanks for the answers.
I have installed many lengths of stovepipe in my career, but always ended the run on the full diameter.
Now I have one, and no "pipe to crimp".
Pretty common for us old tool lovers.
