Razor Cancels
In 1866 Güller & Sons made the first rotating date-wheel cancelers for Swiss Post, Telephone, and Telegraph (PTT). Twenty-three years later in 1889 Frédéric de Coppet patented his first flexible-head canceler mechanism combining both technologies. His patent described the most significant canceler design in the history of the Swiss PTT. These handmade test cancelers were named “razor” cancelers by British collectors in the 1970’s and have become known as “rasierklingenstempel” in Switzerland.
