My GF's brother sent me these photos of a mysterious tool . Looks handy for pulling on all sorts of stuff, but what was its INTENDED use?
"I have had this thing in my tool chest for as long as I can remember. I have no idea how I acquired it, have never used it, and don't know what it is for. If you know what it is, please let me know. It is driving me nuts.
"Only visible marking is "Made in Japan". Only one of the finger rings moves, and when it is squeezed closed, the cam shaped pieces come together tightly as to grip something. Total size is about 2.5" x 2.5".
"Correct answer (or best guess) wins you a prize.
"Thanks for playing!
