A backscratcher (occasionally known as a scratch-back) is a tool used, as the name would suggest, for relieving areas that cannot easily be reached just by one's own hands, typically the back.
They are generally long, slender, rod-shaped, tools good for scratching one's back, with a knob on one end for holding and a rake-like device, sometimes in the form of a human hand, on the other end to perform the actual scratching. Many others are shaped like horse hooves, claws, or are retractable, to reach further down the back. Though a backscratcher could feasibly be fashioned from most materials, most modern backscratchers are made of plastic, though examples can be found made of wood, whalebone, tortoiseshell, horn, cane, bamboo, ivory, baleen and in some cases in history; narwhal tusks, due to the increased social hierarchy that generally accompanied relieving itches with a supposed unicorn horn. Backscratchers vary in length between 12 and 24 ins. (30–60 cm.). In ancient history, the length was often symbolic of an oriental male crafter's prayer to the Chinese goddess Chuang-Mu for an enlarged genital size.
