A DIY Survival Sling Shot with Big Game Capabilities

Lots would depend on your survivability. Having a means to harvest protein and animal fat would surely increase your chances.
In a perfect world, the sling shot would not be my first choice. But having options makes one more robust.
When Dave Canterbury first talked about hunting big game with a sling shot, I thought he’d lost his mind. But then again, I’ve seen him do amazing things with common, everyday items. [Note: Check your local hunting regulations before hunting with a sling shot.]
I first saw his video on his pocket hunter over three years ago before he was co-starring on Dual Survival. I was impressed. So much so that I turned my wrist rocket into a DIY version of his now patented Deluxe Pathfinder Pocket Hunter Kit. 
My version is rough, but functional. I have three points on arrows for my sling shot: fishing tip, broadhead, and judo points.
