A Vietnam War-era P-38 can opener, with a U.S. penny shown for size comparison.. The P-38 (larger variant known as the P-51) is a small can opener that was issued with canned United States military rations from its introduction in 1942 to the end of canned ration issuance in the 1980s. [1]
A drawing from the can opener patent No 19063 by Warner. Ezra J. Warner of Waterbury, Connecticut was an American inventor, who patented his design of a can opener in 1858. A crudely shaped bayonet and sickle combo, his design was widely accepted by the U.S. military during the period of the American Civil War.
A can opener (North American and Australian English) or tin opener (British English) is a mechanical device used to open metal tin cans. Although preservation of food using tin cans had been practiced since at least 1772 in the Netherlands, the first can openers were not patented until 1855 in England and 1858 in the United States.
10 and 15 HP models were nearly the same, aside from motor used. The P-50 was and still is the loudest dual tone siren in the world. The P-15 (Single-tone) and P-50 were still being produced by ASC until 2002 and 2007, under different names (P-15 being the RM-127 and the P-50 being the RM-135/T-135 AC).

The top of the can was cut by pressing the cutting wheel into the can near the edge and rotating it along the can's rim. [5] The need to pierce the can first was a nuisance, and this can opener design has not survived. In 1925, a modern-style opener, equipped with an additional serrated wheel, was invented to improve Lyman's design. [3]
Fraze decided to create an improved beverage opening method that would eliminate the need for a separate device, leading to his creation of the pull-tab opener. His first design included a lever that pierced a hole in the top of the can, but this caused a safety hazard as it produced sharp edges that could cut the user's finger.
