Indispensable survival gear that you’ll actually use when you’re not hanging out with Les Stroud? The Gerber E Tool is definitely in that category. An entrenching tool, or E-tool, is a collapsible spade that’s been used for decades by all branches of the military. Gerber’s version weighs a little over two pounds and folds away nicely – taking up as little space as possible when not in use. It has a built-in pick, powder coated carbon steel blade with a serrated edge and glass filled nylon handle. It’s built to take a beating and last forever. Keep one in your Jeep and always in your pack.
