Someone should tell that guy they've been making those for years....as compound bows.
Looks like all he did was make it more delicate & complicated.
Also, looks like the way the arrow is held in doesn't allow for broadheads. Doesn't make it much good for hunting anything larger than squirrels, IMO.
I'd rather have a big stick in a survival situation. At least you could hit whatever you trapped in the head with it.
