A quirt is a forked type of stock whip which usually has two falls at the end. Sometimes it is called a riding quirt, horse quirt, or a dog quirt.
The quirt, due to its slow action, is not particularly effective as a riding aid for horses, though at times it has been used as a tool of punishment. Rather, it is an effective tool to slap or goad cattle from horseback.
The Irving Klaw photographs of the model Bettie Page often showed her in a dominant pose holding a whip, usually a quirt.
