All joking aside, no backpacker, day-hiker, or wanna-be-MacGyver should be without the well-reviewed CRKT Eat'N Tool. It is at its lowest historical price of $3.45, and is part of the Amazon Add-On program. So if you're already ordering some stuff and especially if you need some filler to get your order up to that magical $25 minimum for free shipping, toss one of these into your cart.
