What are these...

What are these used for...perhaps some kind of tensioner?

Rod bender would be my guess, but I haven't seen one with that many bend points on it.

fence tensioner would be my guess , it would put small wavy bends in a straight fence wire

If you opened the handles to the point that the outside studs is engaged in the half round holes could you get a wire placed in it to align from one side to the other. Then I could see how it could be used to take slack out of a wire.

Thanks for the replies. Unfortunately I can't get my hands on the tool, it belongs to someone some distance from me, else I would test it. It may be a fence tensioner but one wonders how long the strand of wire will remain tense...especially if one owns cattle . Perhaps more a rod bender as Greybreard suggested, maybe a tool made to make a specific design...can't find anything like it on the internet.
