I'm intrigued by the arrowhead but still trying to figure out how/when/where/why to use it. In reading about it somewhere, I saw that the hole in the middle is there in case you want to use it for a spear tip. I could see lashing the back end to the side of a shaft would be doable, but trying to figure out how you would affix it to the end of the stick using the hole. Anyone have a photo of this?
