If I could design and use my Ideal arrow and broadhead is would be this:
The cutters would be like a saw blade, running about 10 inches back up the shaft. Razor sharp pn the front edge, and functioning like a barb. No pulling it out back the way if entered. A piston shaft that upon impact released four spring steel prongs at the end of the blades to prevent further penetration. Double lung one with that, and let 'em run. They won't go far with what that will do to the lungs, and by the time you are on your feet they WILL be dead! Having shot deer with 1950s vintage recurves and Zwickey heads, I never opened one of them up with lungs not completely destroyed. That includes one that I shot from 10-12 feet up a tree and 20 feet behind the deer while it was crawling under a barbed wire fence. I heart shot her, and she basically just sagged to the ground and was dead in seconds. I would guess that the diaphragm trying mightily to get some air into the lungs was as much responsible for the completely wrecked lungs as the arrow that did the wrecking. That was the second deer I ever shot, and the only deer after her that died as quietly as she did were all brain stem shots with a rifle. The truth be told, you wouldn't need any broadhead at all if you could stop the arrow inside the chest. Lungs are that fragile! Once you collapse one lung, the one that's left will start occupying more of the collapsed lungs space and be wrecked also. I cannot remember off hand any deer I double lunged with a rifle that made it more than 70 yards, and they pretty uniformly have a chest full of red soup upon opening. I have often wondered whether such complete destruction of the lungs was from the lungs destroying themselves, or if the bullet did all that damage. I have seen and photographed that kind of damage after an arrow passed through, but arrows often times leave the lungs remarkably intact too.
