All kidding aside, if you're out in the wilderness, or the zombie apocalypse, carry at least one knife with you. It's not only for defending yourself. A knife is in many ways your most important survival tool, and it is for a reason.
"When life becomes difficult—when our resources seem stretched to the breaking point—we can find within us resources of extraordinary fortitude and faith. The goods of heroism are within us all. May we allow courage and honor to define our response to whatever tribulations we face. May we become heroes." –Lloyd D. Newell http://pinterest.com/pin/24066179232775874
