The P-38 is known as a "John Wayne" by the United States Marine Corps, either because of its toughness and dependability, or because of an unsubstantiated story that the actor had been shown in an as-yet-unidentified training film opening a can of K-Rations. The can opener is pocket-sized, approximately 1.5 inches (38 mm) long, and consists of a short metal blade that serves as a handle, with a small, hinged metal tooth that folds out to pierce the can lid. A notch just under the hinge point keeps the opener hooked around 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. The handle portion can also double as a flat-blade screwdriver.
Official military designations for the P-38 include "US ARMY POCKET CAN OPENER" and "OPENER, CAN, HAND, FOLDING, TYPE I". As with some other military terms, e.g., "jeep", the origin of the term is not known with certainty; the P-38 opener coincidentally shares a designation with the Lockheed P-38 Lightning fighter plane, which could allude to its fast performance. However, the P-51 can opener, while larger and easier to use than the P-38 can opener, also has a fighter plane namesake in the North American P-51 Mustang, which is faster and smaller than the P-38 fighter. One rumored explanation for the origin of the name is that the P-38 is approximately 38 mm (1.5 in) long. This explanation also holds for the P-51, which measures approximately 51 mm (2.0 in) in length. United States Army sources, however, indicate that the origin of the name is rooted in the 38 punctures around the circumference of a C-ration can required for opening.
P-38s are no longer used for individual rations by the United States Armed Forces, as canned C-rations were replaced by MRE rations in the 1980s, packed in plastic pouches. The larger P-51s are, however, 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 America and abroad in Afghanistan. The original U.S.-contract P-38 can openers were manufactured by J.W. Speaker Corporation (stamped "US Speaker") and by Washburn Corporation (marked "US Androck"); they were later made by Mallin Hardware (now defunct) of Shelby, Ohio and were variously stamped "US Mallin Shelby O." or "U.S. Shelby Co."

Famous quotes containing the word design:
“Humility is often only the putting on of a submissiveness by which men hope to bring other people to submit to them; it is a more calculated sort of pride, which debases itself with a design of being exalted; and though this vice transform itself into a thousand several shapes, yet the disguise is never more effectual nor more capable of deceiving the world than when concealed under a form of humility.”
—François, Duc De La Rochefoucauld (1613–1680)
“If I commit suicide, it will not be to destroy myself but to put myself back together again. Suicide will be for me only one means of violently reconquering myself, of brutally invading my being, of anticipating the unpredictable approaches of God. By suicide, I reintroduce my design in nature, I shall for the first time give things the shape of my will.”
—Antonin Artaud (1896–1948)
“With wonderful art he grinds into paint for his picture all his moods and experiences, so that all his forces may be brought to the encounter. Apparently writing without a particular design or responsibility, setting down his soliloquies from time to time, taking advantage of all his humors, when at length the hour comes to declare himself, he puts down in plain English, without quotation marks, what he, Thomas Carlyle, is ready to defend in the face of the world.”
—Henry David Thoreau (1817–1862)
