Mine has the red tip insert and a roughly 1" x 1/4" SS small rod-tip coming out and looks like it also has a permanant non-removable rivet of some kind going into the side about 1/2" in from the edge.

Its solid and cannot be removed by anykind of visegrip,etc. Cannot put on a vise and cut with a hacksaw, unless I remove the entire boom from the downrigger,etc. I'm gonna call my plumber buddy to see if he has a heavy duty pipe cutter and go to town with that.
