Credit Card Knife
Most of carry knives on us daily but how many have lost yours whether you set it down after using it or it came unclipped from your pocket? We have all had this happen at one point or another! The Credit Card knife is a handy little backup in your wallet. Folded up, it takes up as much room as a normal credit card but unfold it and you have a regular working knife. Hopefully you'll never need it, but, if you do it will always be there.
