I just stumbled across this, the company Survival Life is having a promotion where they give away free credit card knives. The knives fold into a card and you can keep it in your wallet.
I had to get my friend in the USA to snatch one for me, because it seems to be free for United States only.
Here’s a picture of what the knife looks like and how it works:

The website to get one is http://knifefreebie.com?=2016-knife-giveaway
Any ideas how can we convince them give away some free drawstrings and arrows? 😀
