### 🛠️ Design and Usage

The can opener is approximately 1.5 inches long and consists of a short rectangular metal handle with a small, hinged metal tooth that folds out to pierce the can lid. A notch just below the hinge keeps the opener hooked beneath the rim of the can as the device is “walked” around to cut the lid out. A larger version called the P-51 is somewhat easier to operate thanks to the greater leverage it can generate.([en.wikipedia.org][1])

### 🧭 Historical Context

The designer of the original device that acquired the official U.S. military designations “U.S. ARMY POCKET CAN OPENER” and “OPENER, CAN, HAND, FOLDING, TYPE I”, commonly known as the P-38, is unknown. In spite of widespread claims that the P-38 was designed in a 30-day whirl of inspired effort by the U.S. Army Subsistence Lab in Chicago in 1941, a fully fledged version of the device (differing only in the hole for attaching to a lanyard being on the opposite end of its body) appeared in a 1924 edition of Popular Mechanics. Described as being “designed for campers and Boy Scouts”, it is featured in use in a photograph, with an accompanying full-view illustration. Readers were invited to receive more information on the item at that time by writing to Popular Mechanics, Chicago.([en.wikipedia.org][1])

The P-38 was preceded in U.S. military field rations such as the K-ration and C-ration by then traditional twist-key can opening, where a provided key was inserted in a tab and twisted around a can to peel away a metal sealing strip.([en.wikipedia.org][1])

P-38s are no longer used for individual rations by the U.S. military, as canned C-rations were replaced by MRE rations in the 1980s, packed in plastic pouches. The larger P-51s are included with United States military “Tray Rations” (canned bulk meals). They are also still seen in disaster recovery efforts and have been handed out alongside canned food by rescue organizations, both in the U.S. and abroad.([en.wikipedia.org][1])

### 🧰 Modern Applications

While the P-38 was originally designed for military use, its compact size and functionality have made it popular among campers, hikers, and survivalists. Its small size allows it to be easily carried on a keychain or in a survival kit. Additionally, its design makes it useful for opening cans in emergency situations where larger can openers are unavailable.
