The first thing that came to mind was a 'rug beater'! But that would destroy rugs. Are those metal? Those side arm things?
If so, I am wondering if it might be some type of implement to move bales of hay? But I have seen those before and I think that they are much simpler then that.

I sure that people with farm experience will offer opinions but after seeing the post, you got my curiosity aroused. I just had to offer something but I am probably way off.

Its spring loaded metal opens up wide

It's similar to the tool that picks up an ice block.

only opens 6 inch wide has a 5ft handle like a broom handle

Oh yes. An ice block lifter! I like that a lot.
If you look at old ice harvesting photographs, the ice blocks were a certain thickness. 6" seems right. Width X depth were bigger but thickness might not have been more then 6". It can not be easy to saw through more then 6" of lake ice to harvest blocks. Tools 50-100 years ago had to be limited in some way. A lot of it was done by hand more than 100 years ago.

I can't imagine carrying an ice block with a 5 foot handle. Would also love to know what in the heck that is!

seems too small for ice it is spring-loaded

An ice tool would not be spring-loaded. It seems like it would be used for grabbing (by pushing against) something and pulling it towards you.

@MRTIM22 Could maybe be a blacksmith tong. They have long handles so the blacksmith does not get burned.

maybe a weed remover not sure

Maybe a log puller.

the handle would not hold logs

did not see it in old ice tools

what a mystery. Seems like you would be reaching for something but not a very heavy thing. Fish? Pushing it to grab, then pull. Something underwater?

Something to neuter a hog

don't know maybe it's for weeds or something

search norlund fish gaff I found it but trouble linking the actual page..

Some sort of trap? If it's not triggered until they hit the inner metal piece? Shove into a ground hog hole?
