A riding crop is a short, rigid whip without tails or a lash. Typically less than a metre in length, it is made of fibreglass or cane, and is covered with braided leather, plastic or other material. The business end of the crop will usually finish with a leather loop or flap to limit how much pain and damage it can cause.
The riding crop derives from the crop used by horse riders, but is often made just for the BDSM market or for sale in sex shops.
The most common, and safest, target areas for the use of a riding crop are the buttocks and the rear of the upper thighs.
