My buddy has made some of that style for years. I have a larger one the way he designed it and then one I customized much smaller that holds 4 arrows.
You can just ease the point up to clear the "cup" at the bottom, and out it slides. It slips around to a horizontal position to traverse heavy brush.
Puttin a sharp broadhead back is easy, slide it around, slip the fletch up inside and then OBSERVE your head as you carefly slip it back into the "cup."
The ones I have aren't as "stylized" as the one above, with the cutouts on the "cups" and such, and the stick is fatter...(1 1/2") but basically the same functionally! I love mine!
