If there is one thing I NEVER seem have on me when I need it, it’s one of my awesome multi-purpose tools. The Tool Logic Survival Card 2 is definitely one I wish I had on me more often. This is an ultra-light tool for your wallet, pocket, backpack, car, or drawer at home. It comes complete with a compass, magnesium alloy fire starter, a 1-inch razor sharp serrated blade, LED flashlight, emergency whistle, as well as tweezers and a toothpick. It’s awesome, and will only run you about $19 on Amazon. This is one of those things you didn’t know you needed until you had one.
