First patented can opener

The first tin cans were so thick they had to be hammered open. As cans became thinner, it became possible to invent dedicated can openers. In 1858, Ezra Warner of Waterbury, Connecticut patented the first can opener. The U.S. military used it during the Civil War. In 1866, J. Osterhoudt patented the tin can with a key opener that you can find on sardine cans.

William Lyman – Classic Can Opener

The inventor of the familiar household can opener was William Lyman. William Lyman patented a very easy to use can opener in 1870. The kind with the wheel that rolls and cuts around the rim of a can. The Star Can Company of San Francisco improved William Lyman’s can opener in 1925 by adding a serrated edge to the wheel. An electric version of the same type of can opener was first sold in December of 1931.
