I assume it has something to do with grounding, but I've never seen this before, so I'm curious of its function and need on a particular pole.

Is it "in use" as we see it here, or is this a spare?

Not in use. I'm going to guess a lineman either hung it there or dropped it nearby and forgot about it.

Edit: Example of one in use

This is what it should look like when installed:

And this is what it does when it blows, or when a lineman disconnects it:

I learned about these when a snake climbed the utility pole and blew the fuse leading to our house. Charred snake bits everywhere.

Here's a video where electricians break down the fuse and how it's installed and operated in detail.

It is literally just a big fuse, there's a segment of wire inside that grey tube designed to melt if too much current is going through it. Here's video of one blowing.
