The Joseph Rogers Knife, now known as the Stanley Millennium Year Knife, has more blades than any other knife in the world. Sylvia Kaiser is pictured here unveiling the 1966 blade on July 10, 1966. It was made by Sheffield cutlers Joseph Rodgers & Sons in 1821, with the number of blades matching the year. More blades were added over the years, including special additions for occasions such as the 1953 Coronation and the 1966 World Cup. In the year 2000, a final 2000th silver blade was added bearing the Sheffield hallmark from the Sheffield Assay Office.
