This video didn’t turn out quite the way I wanted it to, but it shows all the steps. So, basically when you have a metal wedge in an axe head it is very soft material. As long as you drill a good pilot hole you can thread a screw into it and And slap it out with a slide hammer. It doesn’t turn out this easy in the video but I promise
It is. Okay Also I did successfully remove the handle without damaging it. I hope you enjoy the video!!
