20. Swiss Army Knife

Year Invented: 1890

Designer: Wester & Co.

The Schweiser Officersmesser (or the Swiss Army Knife as U.S. soldiers called it during World War II, because they couldn't pronounce the German name), was designed by West & Co. for the Swiss Army. The knife was designed to open food containers and disassemble rifles, among other things. The original knife had a blade, reamer, can opener, and screwdriver. In 1891, Elsener took over production of the model. His company Victorinox is the producer of the classic Swiss Army Knife we see and use today.
