I would like to get a few of them. I'm not concerned about two or three ounces for multiples of them. They don't take up any space.
Locking carabiner, slingshot band, HEST or Izula or a handy-dandy RC3 (to make some halfassed arrows out of) and I have an improvised Hawaiian Sling. Or, you have a cut down Cold Steel Blowgun, one hose clamp, slingshot band, same-same.
I took a regular Easton aluminum arrow and using a Judo Point, I put that through a very heavy cardboard shipping box at about 12 feet using a carabiner and a slingshot band. I'm absolutely positive that you could take small to medium sized game with these types of arrowheads up to about 40 feet, depending on how much accuracy you could squeeze out of it.
It's never going to be as accurate as a regular bow and arrow or even a small crossbow, but it's a way to carry something that is viable if you are skilled and everything can fit into a small fannypack or perhaps the RAT PACK pouch, one locking carabiner, slingshot band, three to six arrowheads, the light cordage that is listed as MilSpec that is in the other RAT Kit, etc.
