It reminds me of something from school days, some what like the thing they used to point at maps with.
IMO... Mojax is close.
My guess is also a type of Marlinspke... only it is called a "Fid".
I confess, I had to look up what a Marlinspike is. (learn something new every day!)
There are lots of spellings on this one, so, probably has a long history.
Also, "marling-spike"
