The Tool Logic Survival Card is like a Swiss Army Knife squished flat so you can fold it into your wallet. Bear Grylls would be proud (and have slimmer-looking jeans).
This card doesn’t have a particularly impressive credit limit ($0 at 0% interest) but it can start a fire or be used to kill an enemy. The market prices for those are pretty high depending on which country you’re in.
The card comes equipped with a red LED for signaling passing aircraft at night, a serrated blade made of AUS 8A type stainless steel, a strip of magnesium fire starter (sparked using back of blade), a loud signal whistle to attract your resquers and a lanyard attachment.
It also has a toothpick and a pair of tweezers for if you’re trying to survive an early dinner at the clubhouse of your favorite golf course. Buy it for $20 from Thinkgeek. [Buy it]
