Looks like it may be used to put a crimp in something, Do you have any more context? Did you find this on a farm? A few comapnies make a crimper for jointing rain gutter down spouts, and I'm reminded of this method when looking at this tool. Then again it looks like kind of like a crimping iron that people use on their hair. Maybe for horses?

I have some issues with a few of the tools you mention, however you are not being very specific when naming your tools. When you mention a light tower, are you referring to a an outdoor lighting tower, or are you referring to an indoor work light? When you refer to a chipper shredder, are you referring to a wood chipper commonly used to chip brush, or are you referring to a trash shredder commonly used to reduce the volume of trash? When you refer to a long run fuel tank are you referring to a auxiliary fuel tank for a truck or other vehicle, an accessory external fuel tank for things like generators, or are you referring to a fuel tank that come attached to equipment like a chainsaw? And then You get REALLY specific with a certain saw....
