While we are trying to figure this out, would anyone mind if I asked my learned colleagues to put a caption on this photo? Reason is, I think it belongs in this thread, because I can clearly ask, "What is it?"
You are going to stay up all night scrolling the internet for hammer photos? Well, it's Friday. Make some drinks and roast some peanuts . . .
when red called me city bot i took it is a hint and tried to imagine subways and skyscrapers using this device but i have come up with nothing. it the tool used to open the utilty door thing inside an elevator?
It is a fence tool, used to tighten loose fence wires by using the prongs to twist it and then nailing a staple into/over/through the loops and into the pole to hold everything tight.
I was in a public restroom the other day that had screws with to holes in the head instead of a slot, star or hex. I suppose it could be used for something like that but that seems a little clunky. I'm sticking with fence wire coiler thingy.
