I'm sorry, but I believe it's foolhardy using a glued together wooden arrow shaft, properly footed is one thing, a glued break is another. Having had to take someone to hospital to have a piece of arrow removed from their hand, I would never allow a broken and glued together arrow onto any shoot I was involved in.
The two points where the arrow is under most stress are when it hits the target and more critically when being accelerated on release, these are the two points where the repair is likely to fail. If a sharp piece of wood moving at 150 or so feet per second comes into contact with soft flesh, there is only going to be one winner. Arrow shafts are cheap, the risks are too great to take a chance.
1.You obviously didn't watch or understand the whole video.
2.The arrow through the hand... was it from a spliced arrow?
3. "proper footed arrow" That is still glued with discontinuities in the structure. I show several types of splice/footing in the video (which is why I can assume you didn't watch it right through)
4. Yes I've seen arrows break, but it's always been where they were previously damaged by impact with a tree etc. I've never had one break at a splice.
5. I say it's best for repairs just behind the point. There is no bending force there, and it would be off your hand in the first few inches of travel.(Where it isn't doing 150 fps).
6. Everyone is their own safety officer...
Arrows usually break just behind the pile because the pile gets deflected by a stone, branch etc, the shaft is still flying straight and due to its stiffness and inertia, the pile snaps off. Similarly, impacts further up the shaft can cause damage or fracture the arrow which is often visible if the arrow is inspected before use (many people forget to do this). When the arrow is loosed, the bending force then causes the arrow to break or open up the fracture.
The failures are not due to splices or well made glue joints which are stronger than the parent material*.
Your knee jerk criticism would be better aimed at people who don't inspect arrows before shooting them.
I s'pose I could concede it maybe "foolhardy" for someone with poor DIY/woodworking skills and no understanding of glues to do it, but I am certainly no fool.

*I've made highly stressed flight bows with splices patches and all sorts of glued repairs and features on them in areas subjected to both bending and other loads.
