Humble Bundle has interesting survival related bundle

I’ve bought several book bundles from Humble Bundle. If you are not familiar with the concept, it works like this. With a small amount of money you get books in electronic format (e.g. pdf or epub). Depending on how much you pay your bundle size varies. Typically the whole bundle is something like 20€. Since I’ve used them earlier I got an email that they have a 22 book survival-related bundle available. I decided to buy it just out of curiosity. There is one book about knives and I was happy to notice that it had good overall knowledge about knives. The bundle is available still for a week so there is still time to get yours here.
