Can Opener Day

National Can Opener Day is celebrated on August 24 and recognizes one of the most practical kitchen tools ever invented. The can opener may seem ordinary today, but it made canned food far easier and safer to use at home.

History of National Can Opener Day

The history of the can opener begins with the history of the can itself. Tin-coated food cans were patented in 1810, but for many years there was no proper tool to open them. Early cans were so sturdy that people often had to use a hammer and chisel.

The first patented can openers appeared in the mid-19th century. In 1855, a can-opening tool was patented in Great Britain, and in 1858, Ezra Warner patented the first American can opener. These early tools worked, but they were still awkward and not especially convenient for everyday kitchen use.

A major step forward came in 1870, when William Lyman patented a rotary can opener with a cutting wheel. In 1925, the design improved again when a second wheel was added to grip the rim of the can. That version became the basis for the familiar manual can opener still used in many kitchens today.
