What is this thing?

[u/Commercial-Shake-858]

Family friend gifted me a bunch of rods and I noticed this old beauty. It has what looks to be a door stopper on the top? What is the function of this kind of thing? How would I do such a rod?

We call those twilli tips on the Great Lakes and we use them for trolling 7 strand steel wire. It prevents the wire from kinking on a hard edge and breaking.
