They are serrated on one side. They don't come apart for the other slot. Any ideas and who made them and what their for.

I'll guess hose removal. won't save the hose though.

The one sided cutting edge reminds me of a pecan sheller.

I think they are vintage veterinary or medical forceps.

Do I see remnants of tin plating ... tin plate on iron tools is a tip off of food service. Maybe a lobster claw cracker?

No tin plate. They came from a mechanics toolbox. I also thought about using it as lobster and crab cracker if I can't figure out what it is. Beats using them crappy nut crackers.
