A "field kitchen" item I love is the USGI P-51 can opener. They're small, light, cheap, and simple. I keep several on thin tarred bank line loops clipped on a carabiner in my basement prepper pantry. I keep one in my EDC laptop bag, in my vehicle's get home bag, in hiking packs, etc. Never am I absent an efficient way to opened canned goods, whether in the kitchen, the woods, or during some emergency. I even use them in the kitchen sometimes, when my regular can opener is in the dishwasher.
