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".

I'd say it looks like a tool tor tensioning wires - or strings.
Possibly in the textile business?


My wild guess was that it's for handling film in a dark room.
I have little basis for that guess, and an Internet search did not
validate it.

Since the original questioner seems to have a nautical
connection, I'd think it has some purpose in the marine
world. Perhaps something to do with sailmaking?
