A spur is a metal tool designed to be worn in pairs on the heels of riding boots for the purpose of directing a horse to move forward or laterally while riding. It is usually used to refine the riding aids (commands) and to back up the natural aids (the leg, seat, hands and voice). The spur is used in every equestrian discipline. There are rules in most equestrian organizations about spur design, use and penalties for using spurs in any manner that constitutes animal abuse.

The very old word derives from Anglo-Saxon spura, spora, related to spornan, spurnan, to kick, spurn; cf. Medieval High German Sporn, modern German Sporn, Dutch spoor, Frisian spoar. The generalized sense of "anything that urges on, stimulus" is recorded in English from circa 1390.

The parts of a spur include:

Spurs are usually held on by a leather or leather-like strap, called a spur strap, that goes over the arch of the foot and under the sole in front of the boot heel. Some western designs have a leather strap that goes only over the top, with a heel chain or a rubber "tiedown" instead of a strap under the boot. There are also styles with no straps where the heel band simply is very tight and slips on wedged between the sole and heel of the boot. Some spur designs have a slot for running the spur strap through, others have "buttons," sometimes on the heel band itself and sometimes attached to the heel band by hinges, that allow a strap with buttonholes to be attached.

The Raconteurs /ˌrækɒnˈtɜrz/ (also known as The Saboteurs in Australia) is an American rock band that was formed in Detroit, Michigan, featuring four members known for other musical projects: Jack White (of The White Stripes and The Dead Weather), Brendan Benson (solo), Jack Lawrence (of The Greenhornes, Blanche and The Dead Weather), and Patrick Keeler (also of The Greenhornes).

The band is based in Nashville, Tennessee. According to the band's official website, "The seed was sown in an attic in the middle of a hot summer when friends Jack White and Brendan Benson got together and wrote a song that truly inspired them. This song was 'Steady, As She Goes' and the inspiration led to the creation of a full band with the addition of Lawrence and Keeler." The band came together in Detroit during 2005 and recorded when time allowed for the remainder of the year. Due to the various members' success in other bands, they were quickly dubbed a supergroup. The band, however, asserted they were not, saying that the term implies something pre-planned or temporary, whereas they are actually "a new band made up of old friends."
