Did you know the P38 Can Opener “The little can opener is often called "the Army's best invention".Agree or Disagree?

The tiny, lightweight, P-38 collapsible can opener was developed during World War II, reported to have been a rapid 30 days design project in the summer of 1942 by the U.S. Army Subsistence Research Laboratory in Chicago, IL.

The origin of the name is not clear, like the jeep. Some claim it required exactly 38 punctures around a can to open it. Others say it performed with the speed of a P-38 fighter plane. Whatever the case, it is clear this little device has to be considered one of the most perfect inventions ever designed for use in combat.

According to Gy. Sgt. R. Lee Ermey of the History Channel Mail Call program, Marines in Vietnam called it a "John Wayne" because it was so sturdy and dependable. However, that name may have referred to the P-51, a larger version of the same design, used for larger cans. Whatever the name, the P-38 was a favorite.

Most troops carried it on their dog tags. More than just a can opener, in time the P-38 acquired 1001 uses: all-purpose toothpick, fingernail cleaner, screwdriver, bottle opener, box cutter, letter opener, chisel, scraper, stirrer, etc.

For World War II veterans, and then Korean War and Vietnam vets as well, the P-38 is a souvenir, a bonafide historical artifact worthy of retention. Countless old soldiers still carry a P-38 on their key chain a half century after the fact, or preserve it along with other cherished items from the war.
The P-38 was finally phased out when the C-Rations, last of the canned meals, were replaced by MREs.

The little can opener is often called "the Army's best invention".
A copy of an instruction sheet showing proper use of the P38 from a DoD specification MIL-O-20582A dated 28 November 1956. It gives the official name for the P38: OPENER, CAN, HAND, FOLDING.

Among many other details this specification states in Section 3.3.5 that "Marking for Identification" shall include: "The letters U.S. and the manufacturer's name or trade name..." Packaging is specified as individual envelopes which are then put in boxes of 1000 envelopes (for general use -- special purposes can differ). So if you pick up a P38 that is supposedly "genuine surplus" from the 1950s or so, look for the US and an individual envelope package, such as on the right just below P-38 Can Opener Original package.

The Army's Best Invention
Story by Maj. Renita Foster

It was developed in just 30 days in the summer of 1942 by the Subsistence Research Laboratory in Chicago. And never in its 52-year history has it been known to break, rust, need sharpening or polishing. Perhaps that is why many soldiers, past and present, regard the P-38 C-ration can opener as the Army's best invention.

C-rations have long since been replaced with the more convenient Meals, Ready to Eat, but the fame of the P-38 persists, thanks to the many uses stemming from the unique blend of ingenuity and creativity all soldiers seem to have.

"The P-38 is one of those tools you keep and never want to get rid of," said Sgt. Scott Kiraly, a military policeman. "I've had my P-38 since joining the Army 11 years ago and kept it because I can use it as a screwdriver, knife, anything."

The most vital use of the P-38, however, is the very mission it was designed for, said Fort Monmouth, N.J., garrison commander Col. Paul Baerman.

"When we had C-rations, the P-38 was your access to food; that made it the hierarchy of needs," Baerman said. "Then soldiers discovered it was an extremely simple, lightweight, multipurpose tool. I think in warfare, the simpler something is and the easier access it has, the more you're going to use it. The P-38 had all of those things going for it."

The tool acquired its name from the 38 punctures required to open a C-ration can, and from the boast that it performed with the speed of the World War II P-38 fighter plane.

"Soldiers just took to the P-38 naturally," said World War II veteran John Bandola. "It was our means for eating 90 percent of the time, but we also used it for cleaning boots and fingernails, as a screwdriver, you name it. We all carried it on our dog tags or key rings."

When Bandola attached his first and only P-38 to his key ring a half century ago, it accompanied him to Anzio, Salerno and through northern Italy. It was with him when World War II ended, and it's with him now.

"This P-38 is a symbol of my life then," said Bandola. "The Army, the training, my fellow soldiers, all the times we shared during a world war."

Sgt. Ted Paquet, swing shift supervisor in the Fort Monmouth Provost Marshal's Office, was a 17-year-old seaman serving aboard the amphibious assault ship USS New Orleans during the Vietnam war when he got his first P-38. The ship's mission was to transport Marines off the coast of Da Nang.

On occasional evenings, Marines gathered near Paquet's duty position on the fantail for simple pleasures like "Cokes, cigarettes, conversation and C-rations." It was during one of these nightly sessions that Paquet came in contact with the P-38, or "John Wayne" as it's referred to in the Navy.

Paquet still carries his P-38, and he still finds it useful. While driving with his older brother, Paul, their car's carburetor began to have problems.

"There were no tools in the car and, almost simultaneously, both of us reached for P-38s attached to our key rings," Paquet said with a grin. "We used my P-38 to adjust the flow valve, the car worked perfectly, and we went on our merry way."

Paquet"s P-38 is in a special box with his dog tags, a .50-caliber round from the ship he served on, his Vietnam Service Medal, South Vietnamese money and a surrender leaflet from Operation Desert Storm provided by a nephew.

"It will probably be on my dresser until the day I die," Paquet said.

The feelings veterans have for the P-38 aren't hard to understand, according to 1st Sgt. Steve Wilson of the Chaplain Center and School at Fort Monmouth.

"When you hang on to something for 26 years," he said, "it's very hard to give it up. That's why people keep their P-38 just like they do their dog tags. ... It means a lot. It's become part of you. You remember field problems, jumping at 3 a.m. and moving out. A P-38 has you reliving all the adventures that came with soldiering in the armed forces. Yes, the P-38 opened cans, but it did much more. Any soldier will tell you that."
