A co-worker brought me this to ID. Found on an old farm.
Riveted two-piece tool that opens to 90 degrees, and closes square. Length of 5 3/4". One side has a 5/8" opening and the other has a tab 5/8" in length.
Looks like a crimper of some kind to me, but for large gauge. No hammer marks on it.
The tool has most of what looks like original japanning to me.
I find no numbers or maker marks on it anywhere.

It looks like it could crimp the ferrule on power pole guy wires.  Sure is hefty.

It does have that look, maybe its suppose to be struck with a hammer cause it sure doesn't have a whole lot of handle for squeezing.

Maybe for battery terminal ends.  The lack of hammer marks could be because it never got used, or maybe they used a vise to close it rather than beating on it with a hammer.

That was one of my first thoughts.

I'm with the battery terminal group. I used a similar tool in the 60's. We made up our own cables at the ignition shop I worked in.We used a vise to crimp them
