Every year we gather can openers as they are like gold on the streets.. right behind to dry socks i might guess. A few years ago we got a donation of these little handy dandy items..and now we try to put one in every backpack.
The P-38, developed in 1942,is a small can opener that was issued in the canned field rations of the United States Armed Forces from World War II to the 1980s. Originally designed for and distributed in the K-ration, it was later included in the C-ration. As of 2013, it is still in production and sold on a worldwide market.
