Rouletting uses small cuts in the paper instead of holes. It was used by a number of countries, but is rarely if ever seen on modern stamps. Varieties, often described by philatelists in French terms, include straight cuts (percée en lignes, and percée en lignes colorées with inked cutting bar), arc (percée en arc), sawtooth and the serpentine roulettes (percée en pointe) used by the early stamps of Finland.
A few types of stamps have combined rouletting and perforation, for instance South Africa in 1942.
