The Crisis Card is a titanium credit card knife created by knife maker Mike Snody. He is no longer producing the Crisis Card but there are still a few floating around the internet that you can pick up. Let’s face it, this is not a credit card knife to use for everyday tasks. This card was specifically made to cause bodily harm in self defense situations. It is not a knife you would pack around in your wallet either. The thickness and weight of the knife make it more of a neck knife.
